I have a GL.iNet travel router. When I am not travel, it connects to the router's second WAN port. If my main internet goes down, it takes me 30 seconds to tether my phone and failover manually. My carrier detects and throttles hotspot traffic by measuring packets TTL, so I tweaks the router's iptables to dodge that. Typically I get over 400 Mbps.
From time to time I get the itch to improve my home network uptime, and I have to keep reminding myself that the current setup is fine.
(Tangential, regarding GL.Net routers: I find it satisfying that these routers run OpenWRT out of the box, and top the "Travel routers" category on Amazon: "Overall Pick" and "Amazon's Choice".)
It's probably because usually normal people don't but routers because they get them included in their internet subscription. So the people buying them have a specific reason to that normal routers don't do
I run several GL.Net routers in a mesh across two continents, some have Starlink and cellular, some on regular ol' fiber. They are bulletproof, highly recommend.
I have a friend that is also curious. Their fibre cable was cut by addicts trying to find a source of copper that took a few days to be repaired. Using their hot spot during the outage used up their allotted hot spot bandwidth for the month. My friend would be very interested in how to avoid potential down time in the future.
Pulled the thread on this a bit and it seems that it will be highly carrier-dependent and will likely be flakey if it works at all.
TTL is one of the simplest methods carriers use to detect if there's an extra hop but very unlikely to be their only line of defense against methods like this.
I have AT&T Fiber and 99% of the time it's fantastic, but there are several instances of 30-60 second downtime a day and I have a 5G modem with a Google Fi data sim as a backup. Failover is nearly-instant with a Unifi UDM.
The data sim costs nothing extra on top of my cellular plan and just counts towards my (already very generous) monthly limit of 50GB.
I've just done something similar in response to a heavy storm that's taken out the fiber where I live (7 weeks now, still hasn't been reconnected). Starlink has been a life saver and works flawlessly (~200Mbps, <35ms latency) but I've also added a cheap 4G data SIM in to the mix too for extra resilience (no 5G coverage where I am but 4G gets ~45Mbs with an external antenna).
Had to get this going quickly so used tplink gear as it was readily accessible and surprisingly it's worked quite well. Used an NX210 (for WiFi to house and the backup 4G sim). Connected the NX210's WAN to an ER605, with Starlink router in WAN1 (in bypass mode) and fiber router in WAN2. This gives me instant fail over across all three and the option of load balancing across fiber and starlink (whenever the fiber comes back). Last step was to get an EAP211 so I could share my starlink over to a neighbour who also lost their fiber after the storm. That has worked well too.
* I'm using a residential starlink plan with the full dish (not mini), mounted with their pipe adapter accessory
I also do this. Xfinity went out for a few hours earlier this month and Unifi failed over almost instantly, and within minutes we had high speed internet once I upgraded us. The standby mode would have been plenty for basic web browsing, too.
$5/mo for pretty guaranteed connectivity, plus being able to take it around with me on travels is pretty awesome.
I was paying for gigabit with the local ISP and it slowed down and lost connection so frequently I bought a Starlink (the regular one, not the mini) as a "backup."
As per the usual, my internet went down and I switched to the backup Starlink. After working with it for about a week I cancelled my ISP.
Turned out around 350MBPS down was fine for everything I was doing (and it's way more reliable).
Kinda drifting off topic, but I'm so bitter over this
My girlfriend had been paying for 1Gb fiber for about 5 years at the insistence of the rep because "You stream 4k content and use your internet for work". $110/mo or something. Verizon comes by and sets her up with a modem and an "auto-route smart 2.4GHz/5GHz" router which slots you into a frequency based on...something. Who knows because it didn't work. It just put everything on 2.4GHz.
I noticed while at her house that the internet was painfully slow downloading large files and dug into it.
For those who don't know, 2.4GHz will typically top out around 100Mbps. Around the house you're looking at closer to 50Mbps. With 5Ghz it's much better, about 500Mbps typical, but verizons awful "smart" router just put everything on 2.4GHz.
So for years she had been paying for 1Gbps, Verizon happily taking her money, while she never saw over 100Mbps. It's also not like they tell you anywhere that the router they give you will only realistically offer 1/10th your Gb speed. Such a dumpster tier company. I can only imagine there are tens of thousands being conned by this scheme.
Anyway, I put in a new router and switched to the cheapest plan. The internet is now much faster.
I hate that it works so well these days. I have my antenna right out ground level between the house and trees. Absolute worst case scenario, and it's been rock solid in everything but the heaviest of rain storms for almost a year now. Still, the occasional slowdown or half-second outage really screws up Android's idiotic magic for switching between wifi and cell to the point that my pixel phone is basically useless at home. But that's more of a "google knows best" problem.
XFinity has been terrible lately, and I have a Starlink Mini. XFinity failed today, and I did fallback for a few hours on the Mini. Connectivity was actually better than fiber. If only it worked when it is cloudy -- for $50 on roaming, that's a no-brainer given the exorbitant cost of living in northern cal.
Same remark here. This reads more like paid promotion for UniFi than anything. It should be mentioned that any Linux box can trivially accommodate multiple WAN interfaces. You don't need to pay the UniFi tax for this.
A mobile failover would be cheaper and would give you better connectivity in heavy rain.
A 4G dongle can be purchased for $15, rather than $200 for a Starlink Mini. Then, let's say your main internet source fails and you need to actually use the backup plan beyond the standby amount of 0.5 Mbps. That will cost you a minimum of $50 for Starlink, versus roughly $25 for a month of unlimited cell service. As for standby costs, you can find phone plans for $5 per month tat give a small amount of fast data, as opposed to Starlink's unlimited amount of slow data.
But of course this only works for areas that actually have cell service.
I mean it's more to do with the cool factor of using a satellite, not practical concerns. Practically a mobile failover is superior if you have coverage.
The issue is that mobile is easily overloaded if those around you are also failing over onto it. There are only so many channels available per sector. In my experience, when one of the two incumbent carriers in my area goes down, mobile is immediately useless as a backup.
If you're in a rural area (and heck, even in an urban era) the primary ISP of a region dropping is likely to cause a lot of congestion from cellphones falling back to the operator network.
I found it quite absurd that Spectrum (my cable operator) wants to sell me a modem with integrated 5G/4G backup knowing that as soon as the cable plant drops, hundreds of local phones are going to congest the network as well and my "Invincible WiFi(tm)" will end up dead as a dodo.
I'll just throw a Peplink up and throw the cable and Starlink into it and run that as my load balancer.
> A mobile failover would be cheaper and would give you better connectivity in heavy rain.
When I was living in the rural seaside (literally grapes growing in front of the sea: nice place), when a bad electricity outage would happen it'd take down everything, including the only cell tower we'd be connected to. So no Internet, no mobile phone. No nothing but the laptop's batteries.
There are also people who have the same ISP as the company giving them their phone number: about a year ago in my country (highly modern, western EU country) a major carrier went down for a few hours. Electricity kept working but all the people on that ISP and mobile phone carrier were sorry out of luck. Most shops couldn't accept payments anymore (except cash but people don't use that much here).
Failover on mobile is, for many, the same thing as no failover at all: you may as well not even bother.
Satellite failover, on the other hand, is quite harder to disrupt.
The use case varies but for what it’s worth, most major cellular provider in the US offer fallback Internet plans. Ranges from 10-20 a month depending if you already have a line with them. AT&T has an interesting one where your phone lines hotspot is free and unthrottled whenever your fiber is impacted.
This too depends on which POP/ground station you're landing at.
Maybe less so once the majority of starling satellites are capable of laser communications to route your traffic down to a less saturated ground station.
That works right up until the cell tower goes down too. Then the dongle is a fancy USB decoration, and Starlink Mini, clunky as it is, still has one big advantage: your backup path isn't sharing the same failure mode, which is the whole point even if the setup are uglier and the power draw is worse.
There are probably cheaper options, especially if you want to literally use your smartphone as the hotspot, but the Verizon home backup internet plan I looked at recently is $20 a month (and gives you 7 24-hour periods per month of unlimited data).
The Verizon home router is included when you sign up (you have to return it if you cancel). I bought it out of desperation when my home fiber internet was down all weekend due to a local tech screwing up and unplugging my house from the breakout box on the curb, but given the cost and the normal reliability of my home internet it’s really barely worth it.
Again this is location specific. I have a mini ups on my router/ont. And I assume that my provider also has a UPS, because even when power is out my landline connection just works.
Yup, OP is from the UK. In the UK I got a ThreeUK business SIM for £49 that lasted 2 years with 500GB data. It sits in wan failover and manages about 50mbps which is perfect to keep most services running.
Very much location dependent though. I lived less than a mile from Southampton city centre for a while and could never get anything close to dial-up standard download/upload speeds.
I've heard similar from London residents.
I was looking at the Standby plan a few months ago. There was some talk as to needing to activate it to full speed and price at least once per year or pay an extra fee which makes it a lot less attractive.
I prefer having a 2nd wired connection as my backup. The satellite connection has some clear benefits, but it's still going to outer space. A DOCSIS failover won't suffer from rain fade or a something landing on the antenna.
If I've got a situation so bad it takes out both of my connections I've probably got bigger things to deal with than internet access.
The buried fiber getting cut by is really the only thing that kills the connection. Fiber can go for a long time without power from the local grid infrastructure. My cable provider has a mostly orthogonal failure mode (goes down like clockwork with the grid).
I have a second fiber connection and found out recently that both fibers come along the same route and when a fire took out a utility pole, I lost both connections.
I then found out that all providers bar one (there are 5 or 6) come along the same street.
So if you are going to go with this option choose carefully your providers!
It honestly has to be very strong rain for it to create connection issues. I dont know where you live but here in germany we have that maybe once or twice a year with our antenna.
We've used this in San Francisco to great effect. Once the Internet went down and I took our portable battery to the roof with the Mini and my wife was only a few minutes on her phone hotspot before she was able to have meetings normally. Great functionality.
I live pretty rural and starlink has been worth the price over the last few years. When you compare it to dialup or hughesnet or viasat, it just works.
I wish I had an excuse to actually need this much uptime at home. It's not the hardest thing to jump over to my phone as hotspot the very few times I need it to work.
Man, that 500kbit/s is quite generous for that price, can easily be used to access CCTV cameras in remote areas. I currently use LTE for that and it's 10 eur for 15GB data cap per month for that use case
> Set IPv6 Connection to SLAAC (this is critical - SLAAC must be used, not DHCPv6) [...] Set 'Prefix Delegation Size' to 56
Is this also A UniFi bug, is Starlink doing IPv6 address assignment in a weird way, or is this a normal/RFC-compliant way of assigning a /56 subnet to a router?
I always assumed routeable prefixes on v6 require DHCPv6 (except for hacks like RFC 7278 and /64 subnets)?
I use Starlink as a backup provider, have done loads of work to tunnel public IPs via it, automatically fail over traffic etc, yet had no idea they supported public IPv6 subnets until reading this article.
Whatever one might think about Elon Musk's posts on X, the engineering and achievements coming out of SpaceX are genuinely extraordinary and deserve a lot of respect.
Every so often I do the numbers on a backup Internet connection and decide that it's not worth it, but understand that it is useful for peace of mind reasons. My Internet is just too reliable. When I'm out of contract with my current provider I'll need to reconsider this as the supplier I'm likely to move to has no obvious/simple/integrated backup option.
tl;dr FTTP. A single outage event in 16 months, lasted 40 minutes, whilst asleep.
I'm in the UK and have FTTP through BT. Way back when I also purchased the 4G backup option (Hybrid Connect) that comes with this service. That's an extra £7.50/mo when taken as part of the usual 24-month contract. It's simple to setup and doesn't require any specific maintenance.
Looking back at the logs it's clear (from an actual usage perspective) it's not been worth the £7.50/mo I've been paying for it, but I'll admit it helped give me peace of mind when I was on-call for work so it is easy to justify.
The BT supplied router (which is required if you want to use their 4G backup hardware) keeps a log of "Resilience events".
In the 16 months I've had FTTP it has had exactly one "resilience event". A 40m11s outage that started at 00:20:05 on 28/11/2025. I was unaware of this outage as I was asleep.
It was really useful when I moved house though. I was in the middle of a 24-month contract with BT at my old address so I ported my contract to my new address. This meant they had to come round and install FTTP at the new property, which they couldn't do for a couple of weeks, so I was without home Internet for these two weeks.
Luckily the 4G "Hybrid Connect" backup device wasn't geo-locked (or if it was maybe BT overlooked it given there was an outstanding "Moving house" order on the account) and so it worked perfectly for the ~2 weeks between moving in and FTTP being installed. If this hadn't worked then a temporary 4G router would have worked just as well.
I had a bunch of "resilience events" for this period (it wasn't one continuous event as I was moving/restarting the broadband router for various reasons). During those 13 days the logs show 163GB download and 25GB upload. That's an average of ~150KBps (note the capital B there, in bits-per-second it is ~1.1Mbps) download.
In the 26 months prior to moving (where I was on ~75Mbps FTTC with BT) I had 3 "resilience events". 17m36s, 47m7s, 31m22s. All between midnight and 4am where I wouldn't have noticed, these were also within 1 month of each other, the other 25 months had no problems at all. None.
When my current contract comes to an end I'll move to a different supplier (probably Community Fibre as I can get symmetric 5Gbps for less than I'm paying BT for 1Gbps/120Mbps) and then not worry about a backup. If it is less reliable then I'll look for a solution then.
My current backup is simply to hotspot on my mobile with 5G (good signal here). Doesn't help the others in the house but they can fend for themselves. Neighbours have different suppliers or technologies (DOCSIS vs FTTP) so swapping wifi details would also be an option.
As others have pointed out, a local power-cut that takes out of the FTTP cabinet could easily take out the local 4G/5G masts making a 4G backup solution useless. If this happens I can just take my laptop to a nearby cafe or the co-working space I use. That kind of outage is very rare though round here.
Then again with the sums involved (under £10/month extra) it may just be easier (for peace of mind again) to just plump for something that doesn't really make amazing financial sense as it's just the cost of a pint or two a month.
I was with a small company called BRSK who did the FTTP rollout in my area, I think they have changed hands a few times now, but the sheer reliability was legit 5-9s. I don't legally fully understand how small companies ended up getting lots of money from the government for FTTP but they absolutely crushed it in my area. Shame they got mega review-bombed because they installed telegraph poles outside people's houses and that's apparently evil
And yet again 50% of the work is working around IPv6 nonsense. I long for the day when we give up on it and try again (with proper DHCP and proper support for NAT)
> Modern journalism goes for clicks, which means generating outrage.
Is this about journalists talking about musk, or about musk himself? I mostly learn about his views through his own tweets that twitter always makes sure to serve me in my home page, and "goes for clicks"/"generating outrage" seems to fit well how musk uses his platform. In any case, his politics seem awful to me even without any journalistic mediation of them.
Did you see what DOGE did to the government? In particular to USAID? Estimates are that this has already killed hundreds of thousands of people who relied on that aid.
The issue isn't just Musk's politics. It's that his actions have been evil, the kind of negative impact that major wars have.
We're talking something like 1 million dead people per year with a quarter of those being children. For a level of assistance that cost the US nothing (0.43% of federal spending). This is an evil that in a few years puts you on the list of biggest mass murderers in history.
What makes Musk different than Blackrock for instance? Or Monsanto, or Shell, or any corporation both of us rely on and support, in return for being able to eat, fuel our car, etc.
Is it because Musk isn't lobbying behind the corporation but doing it publically?
I truly don't understand where ya'll draw the line.
I truly don't care what other people do or want, I just look to ensure I can live the life I desire while respecting that which others want or impose.
As if me being angry or boycotting them will change their hearts. If it changes anything it's their tactics (more deception).
Another example is AI. I despise it, and honestly think it's evil. Yet I'm using it to secure financial stability in a way that does not require AI to sustain.
So when AI takes over my programming job I have the alternative already running, thanks to AI.
Don't reject the massive advantages of Starlink because of a man, just as you're not actively starving yourself despite our food supply being basically poison, caused by boards of men.
Choosing to stand up for your principles in one instance, doesn't mean you suddenly have to fight all the battles all at once, even those that aren't apparent you (yet). How do you know this person is not choosing principles on other occasions already? IMO doing this is better than doing nothing. You can always choose to pick up more battles later. Other people can fight the other fights. Everyone always choosing self over principles will be worse in the long run
This passionate apologia of nihilism is not consistent with not caring what other people do or want. If "virtue signalling" elicits such reaction, perhaps it's actually working. Besides, voting with your wallet, an actual tangible action, is not virtue signalling.

You have a service you want, but subscribing to it is a clear and direct way to financially support the advancement of fascist, extremist political groups and regimes pushing alarmingly racist and xenophobic policies not only in the US but also across the world.
Does your convenience justify a totalitarian shift? I don't think so. Do you think it does?
I stumbled on a long article post by John Conrad @johnkonrad about War on Rocks on X that explains this mentality. I haven't seen it put this way before.
> OP doesn't live in the US, so maybe they don't feel this quite as acutely
It's the same sentiment in large parts of Europe, and a major reason for dropping Tesla sales. He actively supports right-wing, eurosceptic politics and parties in several European countries.
Starlink amazing solution to a problem that should have been solved by governments years ago, the USA has power to most homes and USPS will deliver anywhere so why do we not have the same for internet? God knows

> My carrier detects and throttles hotspot traffic by measuring packets TTL, so I tweaks the router's iptables to dodge that.
Could you elaborate on this?
Some mobile phone providers check the packet TTL to limit tethering.
Network packets commonly have start with default TTL values of 64, 128, or 255. Each hop in the network subtracts 1.
When phone connects direct to carrier (cell tower, I assume) the carrier will see TTL of 64.
A laptop tethered to a phone introduces a hop so laptop-to-phone TTL is 64, phone-to-carrier TTL is 63.
Carriers can then limit bandwidth if network packet that don't have a common TTL.
For `iptables` look at `--ttl-inc 1` (to add back the 1 so 63 => 64) or `--ttl-set 64`.
Alternatively, you set the tethered devices to use a TTL of 65, e.g. linux/mac `sysctl -w net.inet.ip.ttl=65`
3 replies →
You can easily manipulate and set TTL to whatever is needed with a Mikrotik router. Override TTL for all devices behind it.

Sure, it's widely known.
Default TTL is usually 64.
Phone traffic TTL is 64.
But when behind the phone-as-router/gateway, compy traffic TTL is...63!
Out of curiosity what carrier are you using?
Pulled the thread on this a bit and it seems that it will be highly carrier-dependent and will likely be flakey if it works at all.
TTL is one of the simplest methods carriers use to detect if there's an extra hop but very unlikely to be their only line of defense against methods like this.
Is your phone connected to the router through a cable or wirelessly?
They can do both - cable or bluetooth. Don't think wifi

When I was living in the rural seaside (literally grapes growing in front of the sea: nice place), when a bad electricity outage would happen it'd take down everything, including the only cell tower we'd be connected to. So no Internet, no mobile phone. No nothing but the laptop's batteries.
There are also people who have the same ISP as the company giving them their phone number: about a year ago in my country (highly modern, western EU country) a major carrier went down for a few hours. Electricity kept working but all the people on that ISP and mobile phone carrier were sorry out of luck. Most shops couldn't accept payments anymore (except cash but people don't use that much here).
Failover on mobile is, for many, the same thing as no failover at all: you may as well not even bother.
Satellite failover, on the other hand, is quite harder to disrupt.

The use case varies but for what it’s worth, most major cellular provider in the US offer fallback Internet plans. Ranges from 10-20 a month depending if you already have a line with them. AT&T has an interesting one where your phone lines hotspot is free and unthrottled whenever your fiber is impacted.
Yeah but if you need Internet failover, cell phone towers are likely flooded. Starlink will be much more available (probably).
This too depends on which POP/ground station you're landing at.
Maybe less so once the majority of starling satellites are capable of laser communications to route your traffic down to a less saturated ground station.

Using a 4g/5g router is much easier and probably cheaper/power efficient.
Depending on your area you don't even need an external one. A simple 4g dongle would do.
That works right up until the cell tower goes down too. Then the dongle is a fancy USB decoration, and Starlink Mini, clunky as it is, still has one big advantage: your backup path isn't sharing the same failure mode, which is the whole point even if the setup are uglier and the power draw is worse.
100%. In my area unfortunately my ISP shares the same infra as my mobile provider. Many times they’ve gone out together.
There are probably cheaper options, especially if you want to literally use your smartphone as the hotspot, but the Verizon home backup internet plan I looked at recently is $20 a month (and gives you 7 24-hour periods per month of unlimited data).
The Verizon home router is included when you sign up (you have to return it if you cancel). I bought it out of desperation when my home fiber internet was down all weekend due to a local tech screwing up and unplugging my house from the breakout box on the curb, but given the cost and the normal reliability of my home internet it’s really barely worth it.
Unifi (which the OP uses) even has dedicated devices for this type of failover: https://help.ui.com/hc/en-us/articles/29887153953559-UniFi-5...
Spendy though.
The Unifi 5G modem for the UK [1] is £378 (~USD500) and that's just the hardware, you still have to pay for a suitable SIM.
I can see why some people are drawn to the Starlink option at 1/3 of that price.

When here is local power outage and everyone switches to 4g/5g, it is overwhelmed and unusable.
Again this is location specific. I have a mini ups on my router/ont. And I assume that my provider also has a UPS, because even when power is out my landline connection just works.
2 replies →
And the local power outage takes out the 4g/5g mast too.
Yup, OP is from the UK. In the UK I got a ThreeUK business SIM for £49 that lasted 2 years with 500GB data. It sits in wan failover and manages about 50mbps which is perfect to keep most services running.
Is that £49 a month, or £49 for the 500GB data? Sounds useful!
Very much location dependent though. I lived less than a mile from Southampton city centre for a while and could never get anything close to dial-up standard download/upload speeds. I've heard similar from London residents.

I was looking at the Standby plan a few months ago. There was some talk as to needing to activate it to full speed and price at least once per year or pay an extra fee which makes it a lot less attractive.
I prefer having a 2nd wired connection as my backup. The satellite connection has some clear benefits, but it's still going to outer space. A DOCSIS failover won't suffer from rain fade or a something landing on the antenna.
If I've got a situation so bad it takes out both of my connections I've probably got bigger things to deal with than internet access.
The buried fiber getting cut by is really the only thing that kills the connection. Fiber can go for a long time without power from the local grid infrastructure. My cable provider has a mostly orthogonal failure mode (goes down like clockwork with the grid).
I have a second fiber connection and found out recently that both fibers come along the same route and when a fire took out a utility pole, I lost both connections.
I then found out that all providers bar one (there are 5 or 6) come along the same street.
So if you are going to go with this option choose carefully your providers!
Five or six! My kingdom for one fiber provider.
This entirely.
“I like docsis”… cool, it turns to fiber 500ft after your house.

It honestly has to be very strong rain for it to create connection issues. I dont know where you live but here in germany we have that maybe once or twice a year with our antenna.
We've used this in San Francisco to great effect. Once the Internet went down and I took our portable battery to the roof with the Mini and my wife was only a few minutes on her phone hotspot before she was able to have meetings normally. Great functionality.
I live pretty rural and starlink has been worth the price over the last few years. When you compare it to dialup or hughesnet or viasat, it just works.
Same, right now it's great. I imagine we'll get enshittification soon enough when starlink gets enough lock in, but right now it's good.
TIL standby mode. Is that enough to operate a remote webcam? Not real time video feed but say uploading a photo every 1 minute or so
Apparently you get unlimited data capped at 500 kbit/s. So that would be a clear "yes".
Depending on a whole bunch of things but a 200KB photo once a minute might be in the realms of LoRa. You could get the data out for free.
The 500Kbps of Starlink would be close enough for a 500KB photo every 10 seconds or so assuming typical packet overheads.
For security applications where most of the image doesn't change, 500 Kbps is fine for low resolution video streaming.
You can find something similar with IOT sims. And then you just need a standard 4g/5g dongle/router
Care to point me to it? The best I can find searching a bit with unlimited data is capped to 64 kbps for $100/yr, which is quite a bit worse.
Be aware of rain fade. Unit is only rated to operate up to 50 C Hail impact protection for antenna ?
Do the same thing with an edge router x and 4g pay as you go t-mobile mifi.
I wish I had an excuse to actually need this much uptime at home. It's not the hardest thing to jump over to my phone as hotspot the very few times I need it to work.
Man, that 500kbit/s is quite generous for that price, can easily be used to access CCTV cameras in remote areas. I currently use LTE for that and it's 10 eur for 15GB data cap per month for that use case
> Set IPv6 Connection to SLAAC (this is critical - SLAAC must be used, not DHCPv6) [...] Set 'Prefix Delegation Size' to 56
Is this also A UniFi bug, is Starlink doing IPv6 address assignment in a weird way, or is this a normal/RFC-compliant way of assigning a /56 subnet to a router?
I always assumed routeable prefixes on v6 require DHCPv6 (except for hacks like RFC 7278 and /64 subnets)?
I use Starlink as a backup provider, have done loads of work to tunnel public IPs via it, automatically fail over traffic etc, yet had no idea they supported public IPv6 subnets until reading this article.
Whatever one might think about Elon Musk's posts on X, the engineering and achievements coming out of SpaceX are genuinely extraordinary and deserve a lot of respect.

Every so often I do the numbers on a backup Internet connection and decide that it's not worth it, but understand that it is useful for peace of mind reasons. My Internet is just too reliable. When I'm out of contract with my current provider I'll need to reconsider this as the supplier I'm likely to move to has no obvious/simple/integrated backup option.
tl;dr FTTP. A single outage event in 16 months, lasted 40 minutes, whilst asleep.
I'm in the UK and have FTTP through BT. Way back when I also purchased the 4G backup option (Hybrid Connect) that comes with this service. That's an extra £7.50/mo when taken as part of the usual 24-month contract. It's simple to setup and doesn't require any specific maintenance.
Looking back at the logs it's clear (from an actual usage perspective) it's not been worth the £7.50/mo I've been paying for it, but I'll admit it helped give me peace of mind when I was on-call for work so it is easy to justify.
The BT supplied router (which is required if you want to use their 4G backup hardware) keeps a log of "Resilience events".
In the 16 months I've had FTTP it has had exactly one "resilience event". A 40m11s outage that started at 00:20:05 on 28/11/2025. I was unaware of this outage as I was asleep.
It was really useful when I moved house though. I was in the middle of a 24-month contract with BT at my old address so I ported my contract to my new address. This meant they had to come round and install FTTP at the new property, which they couldn't do for a couple of weeks, so I was without home Internet for these two weeks.
Luckily the 4G "Hybrid Connect" backup device wasn't geo-locked (or if it was maybe BT overlooked it given there was an outstanding "Moving house" order on the account) and so it worked perfectly for the ~2 weeks between moving in and FTTP being installed. If this hadn't worked then a temporary 4G router would have worked just as well.
I had a bunch of "resilience events" for this period (it wasn't one continuous event as I was moving/restarting the broadband router for various reasons). During those 13 days the logs show 163GB download and 25GB upload. That's an average of ~150KBps (note the capital B there, in bits-per-second it is ~1.1Mbps) download.
In the 26 months prior to moving (where I was on ~75Mbps FTTC with BT) I had 3 "resilience events". 17m36s, 47m7s, 31m22s. All between midnight and 4am where I wouldn't have noticed, these were also within 1 month of each other, the other 25 months had no problems at all. None.
When my current contract comes to an end I'll move to a different supplier (probably Community Fibre as I can get symmetric 5Gbps for less than I'm paying BT for 1Gbps/120Mbps) and then not worry about a backup. If it is less reliable then I'll look for a solution then.
My current backup is simply to hotspot on my mobile with 5G (good signal here). Doesn't help the others in the house but they can fend for themselves. Neighbours have different suppliers or technologies (DOCSIS vs FTTP) so swapping wifi details would also be an option.
As others have pointed out, a local power-cut that takes out of the FTTP cabinet could easily take out the local 4G/5G masts making a 4G backup solution useless. If this happens I can just take my laptop to a nearby cafe or the co-working space I use. That kind of outage is very rare though round here.
Then again with the sums involved (under £10/month extra) it may just be easier (for peace of mind again) to just plump for something that doesn't really make amazing financial sense as it's just the cost of a pint or two a month.
I was with a small company called BRSK who did the FTTP rollout in my area, I think they have changed hands a few times now, but the sheer reliability was legit 5-9s. I don't legally fully understand how small companies ended up getting lots of money from the government for FTTP but they absolutely crushed it in my area. Shame they got mega review-bombed because they installed telegraph poles outside people's houses and that's apparently evil
> the sheer reliability was legit 5-9s
That made me think about mine...
a) FTTC:
25 months and only outages were 17m36s, 47m7s, 31m22s gives ~99.991
b) FTTP:
16 months and a single 40m11s outage gives ~99.994
(Both using 30 day months, the answers remain the same to 5sf even if I calculate the durations more accurately.)
I'd happily take 4 nines for residential broadband.

I guarantee you, you’re giving money to people much worse than him every time you shop, without realizing it.
Yeah but that doesn't mean that you should give money to people where you know for sure they suck?
For all other cases, you can still try to not give money to people who suck by going for fair trade products and stuff like that.
> I guarantee you, you’re giving money to people much worse than him every time you shop, without realizing it.
Your assumption lies on the "without realizing it".
If you realize how bad the people are, you can do something about it.
The likes of Musk are extremely bad, and have been personally responsible for many, many abhorrent developments in both national and foreign stages.
Thus, it's natural that people avoid anything which is directly and indirectly tied to the likes of Elon Musk.
Don't you agree?

> Modern journalism goes for clicks, which means generating outrage.
Is this about journalists talking about musk, or about musk himself? I mostly learn about his views through his own tweets that twitter always makes sure to serve me in my home page, and "goes for clicks"/"generating outrage" seems to fit well how musk uses his platform. In any case, his politics seem awful to me even without any journalistic mediation of them.
I've seen his tweets direct. You don't have to spin his opinions for them to look horrendous.
How does you spin his reply of "100%" to a "white solidarity is the only way to survive" tweet as not very extreme?
His own X posts make him out to be an apartheid apologist and white nationalist.
> His politics are less extreme than you probably think.
Just look at the whole DOGE mess. Brush aside anything you believe can be brushed aside due to incompetence. Look at the result.

Did you see what DOGE did to the government? In particular to USAID? Estimates are that this has already killed hundreds of thousands of people who relied on that aid.
The issue isn't just Musk's politics. It's that his actions have been evil, the kind of negative impact that major wars have.
We're talking something like 1 million dead people per year with a quarter of those being children. For a level of assistance that cost the US nothing (0.43% of federal spending). This is an evil that in a few years puts you on the list of biggest mass murderers in history.

I don't understand this mentality.
What makes Musk different than Blackrock for instance? Or Monsanto, or Shell, or any corporation both of us rely on and support, in return for being able to eat, fuel our car, etc.
Is it because Musk isn't lobbying behind the corporation but doing it publically?
I truly don't understand where ya'll draw the line.
I truly don't care what other people do or want, I just look to ensure I can live the life I desire while respecting that which others want or impose. As if me being angry or boycotting them will change their hearts. If it changes anything it's their tactics (more deception).
Another example is AI. I despise it, and honestly think it's evil. Yet I'm using it to secure financial stability in a way that does not require AI to sustain.
So when AI takes over my programming job I have the alternative already running, thanks to AI.
Don't reject the massive advantages of Starlink because of a man, just as you're not actively starving yourself despite our food supply being basically poison, caused by boards of men.
Choosing to stand up for your principles in one instance, doesn't mean you suddenly have to fight all the battles all at once, even those that aren't apparent you (yet). How do you know this person is not choosing principles on other occasions already? IMO doing this is better than doing nothing. You can always choose to pick up more battles later. Other people can fight the other fights. Everyone always choosing self over principles will be worse in the long run
