Verizon outages reported across U.S.

25 days ago (firstcoastnews.com)

I see multiple posts here speculating on cyberattack—as opposed to "we pushed a bad configuration update which messed everything up irreparably"—you know, like it has been every other time before this.

E.g., Cloudflare, Meta (who in doing so also locked themselves out of the building), and didn't some bumbling major Canadian telco knock themselves offline for like a week not too long ago?

  • One of these times they will be right and you will never hear the end of the time they were first to recognize the start of a cyberattack.

    • It works both ways, a lot of people also take the "nothing ever happens" position and it is true that most of the time "nothing ever happens", so by taking that position, they're right 99% of the time and sound smart

    • Your post reflects another online observation. With the rise of online sports books, this sort of predictive doomerism has flooded almost every team's online comment section. It no longer feel like fandom or community in the same way. Just lots of voices that will be glad to say, "I told you so," in the loss and crickets with the W. Wish there was some accountability mechanism for all the negative noise broadcasted into the channel.

  • I worked at a major ISP and we had a similar situation where the North East went down and the RC was a fiber cut at a major node in Philly.

    These network topologies are incredibly complex and edges you think wouldn't exist have ways of suddenly appearing when things go awry.

  • Cyberattacks are a good scapegoat for any large incompetent non-tech company that is unable to admit a mistake. (tech companies are more open to admitting actual mistakes - and reluctant to disclose cyberattacks even if there actually was one - where as non-tech ones would rather allude to an attack than admit a mistake)

    Cyberattack scenarios pretty much never make sense in case of complete outages; if you have the access required to cause such an outage it’s always more profitable to keep this access and use it for covert spying/targeted attacks or save it for later than to burn it by causing a massive, visible problem.

  • Verizon had issues routing calls to a provider I'm aware of yesterday, and had to make some sort of change today to fix it. I'm definitely thinking bad configuration update.

  • It's affecting every mobile carrier (ATT, TMO), not just Verizon

    • No, it's affecting Verizon and people on ATT & TMO trying to get in touch with the Verizon customers who are affected.

      Note the tiny fraction of people reporting for ATT & TMO compared to Verizon on DownDetector: https://downdetector.com/

      (You have to click the links to see actual magnitude because the graphs are scaled to show relative outage within a given service -- order of 150k for Verizon vs 1.5k for the others.)

For those who weren't aware: Verizon got a new CEO late last year and laid off 15% of the workforce (15,000 people). This included people working in network, IT and cyber security.

  • Everyone is always so negative about these outages, but if we look at the details we see it was a win as long as they maintain 85% up time.

  • 15% seems like the magic number. It seems like many corporations layoff approximately that fraction of their workforce; it's hard to believe it's coincidence.

  • Is there a substantive connection?

    Like all the doom and gloom after the Twitter layoffs predicting the site would implode and go permanently offline "within a month" which...never happened.

    It's also ironic in the sense it implies the indignant people were so bad at their jobs they designed and built a system so fragile it would collapse without constant intervention from thousands of individuals.

    You do realize it's possible for an organization to be overstaffed?

    • This is unrealistic and seems to be biased by some kind of broad un-focused hostility. Yes, maybe they were overstaffed. But it's reasonable to suspect that leadership overcut, given the current climate and the number being 15,000. Your characterization of Twitter predictions relies on cherry-picking and ignores the actual impacts, and there's no evidence that the system goes down without "constant" intervention from "thousands". Your tone also implies that large, complex systems, even if designed well, don't normally require a lot of maintenance from many people.

    • Verizon is a traditional for-profit telco. Not some VC funded startup trying to hit a burn rate. Very unlikely they were overstaffed by 15k, sounds more like overzealous cost-cutting to hit a quarterly target.

    • There were issues and outages for weeks after the layoffs though. Many people also believe its overrun with far more bots than when it had more robust content moderation tools and teams.

      Also things break. Vulnerabilities come along that need to be carefully patched and deployed. Tools and packages get depreciated. Updates can be done to save compute, and money. Things don't just hum along with zero intervention by no one for years and years.

    • Real-time multi-directional communications over massive geographic areas with tens of thousands of physical cell sites connected to ~140M devices vs... public text messages with media.

      I realize your point, but its fair to say maintaining a nationwide physical wireless infrastructure may not be the same as hosting tweets, particularly when outages strike.

    • Slight sarcasm ahead—fair warning.

      When Twitter did, its CEO may have slept at the office for weeks to make sure problems were resolved.

      On the other hand, the Verizon CEO may be shopping for a new boat

    • > the doom and gloom after the Twitter layoffs predicting the site would implode and go permanently offline "within a month" which...never happened.

      Many think Twitter has imploded, though it's online.

      > You do realize it's possible for an organization to be overstaffed?

      It's possible to be understaffed or appropriately staffed. Anything is possible!

  • If you’ve got 100k people to run something that should run essentially on autopilot, you’ve got much deeper problems where merely laying off selected chunks of people will no longer help. The whole company is rotten and the only way is to start from scratch and not make the mistakes that led you to accumulate 100k people.

    I can't even begin to imagine what those 100k people actually do. For starters, none of the telcos actually develop their own equipment - they buy pre-made from vendors like Ericsson. Often that includes ongoing maintenance too. The only "engineering" is building the back-office and customer-facing UIs, and even that is often outsourced (as a rule of thumb, if something can be outsourced, telcos will do it: https://berthub.eu/articles/posts/5g-elephant-in-the-room/).

    Customer service might be part of that number (assuming that too isn't outsourced), but even then 100k feels extreme.

    10k is ok although leaning on the more bloated side. But 100k?

    • Obviously, you know exactly how to run a major telecomm operation ten times as efficiently as the dominant operator in the most prosperous nation on earth — you are wasting your skills and should absolutely be given funding to disrupt them and make Billions!! What is holding you back from joining the Oligarchs?

    • The problem with being a nationwide ISP - and Verizon runs mobile phones, fiber and all kinds of other stuff - is that you need lots of hands across the country. A lot of stuff can be done remotely and with automation, but often enough you still need actual physical hands on site, and you can't just say "eh, we'll come around tomorrow, we can't make it there faster".

Recently downloaded bitchat so I can contact my family members if outages like this happen when we’re out and about. I got a few T1000 cards for meshtastic but there’s just too much friction to teach my spouse and others how and when to use it. I wish haloW was built into phones which would make long range local communication much better.

  • Does bitchat work during a phone outage? Range on BLE is pretty low, right, so I'd expect it to not do much unless you happen to live in an area where there are bitchat users every 100 ft or so.

    I'm in a similar boat to you in wanting a LoRa mesh. I tried out MeshCore on the LilyGo T-Deck+ hoping it would be a device I could hand out to family members, but I found the hardware and software disappointing.[0] But I'm weirdly tempted to try the LilyGo Pager.

    [0] https://mtlynch.io/first-impressions-of-meshcore/#testing-th...

    • Unfortunately as you said, the range is abysmal since it uses BLE. It’s barely enough for a box store but it’s better than nothing. I like the idea of the lilygo pager too. I first thought it was e-ink from some of the pictures but sadly it was not.

I got sniped away from Visible (Verizon MVNO) by US Mobile (multi-carrier MVNO) during a Black Friday sale. USM has an interesting thing where you can actually get a separate eSIM for each of the major carriers, and switch between them. I was curious so I signed up for all 3. It's been interesting to see how the signals vary from location to location, and at least a couple times I've been able to get significantly better signal by switching.

The main downside is that you have different numbers for each eSIM, but that doesn't really affect me because I use Google Voice for SMS.

  • I switched to US Mobile a long time ago just due to pricing. I was WFH most days of the week (before Covid) so I could do minimal data and pay around $100/yr for unlimited talk/text. Now, I do unlimited everything as I commute 5 days each week, but it's only $200/yr. Still significant savings.

  • I like US Mobile a lot. That they're able to get postpaid priority on Dark Star is amazing.

    I use them for my work phone, but there are a few things keeping me from switching away from T-Mobile for my personal lines (and I'd VERY MUCH like to switch):

    - I have a family plan wherein I pay something like $254/mo for seven voice/data lines, two smartwatch lines and two tablet data lines. The phone lines all have unlimited data at full speed.

    - T-Satellite just launched (wherein your phone uses Starlink when terrestrial towers aren't available). I'm not in this situation often but it can be useful.

    - My plan provides free Wi-Fi on United. I fly a lot and use this benefit all of the time. Losing it would negate the savings I'd rack up from switching to US Mobile.

  • I really love US Mobile. I was a flagship postpaid $90/mo VZW customer for a decade and was so hesitant to switch. It's been 4 years now, and all I can say is that I can't believe I waited so long.

  • I'm considering switching to US Mobile from Verizon-- it seems way cheaper, and you can still use the Verizon network. Any downsides I should know?

    • I started mid last year and haven't run into any problems. Haven't needed to switch off of Dark Star yet.

      I was previously on Google Fi, and MVNO roaming is bloody fantastic - I always had reception.

    • I switched over a year ago and all I can say is … it’s been excellent. $25/month per line is perfect and service is just as good as our Verizon postpaid.

  • Ive had many issues where services can't verify the GV phone number - cause they know it's GV. Does this still happen?

    • Yup! Tip: lock em in and verify a regular cell phone number and then port it. They can probably make it work for you if it’s like a bank, otherwise yolo.

Lol it's network core. Postpaid users on Verizon branded accounts affected. Most MVNO's just fine (checked US Mobile and Visible, different cores... and they are working fine on the Verizon towers)

  • Further info: https://old.reddit.com/r/cellmapper/comments/1qcwj48/observa...

    • T-Mobile had this issue 5 years or so ago where the IMS core went down due to fiber issues at one of their major backbone providers (pretty sure it was zayo).

      As I've said elsewhere, never underestimate Verizon's incompetence. A couple years ago they shut down vtext service which also happened to host their UAprof's for most Android phones. Without a working link to these descriptors, those devices would download any MMS (pre-RCS picture messages) in compatibility mode at the lowest resolution.

Verizon acknowledged the issue: https://xcancel.com/VerizonNews/status/2011500483072954495

https://downdetector.com/ shows verizon, tmobile, and att. BUT if you look at the magnitude of the outages for tmobile and att vs verizon it's fractions of a percent. Likely those people with tmobile and att reporting when they have trouble communicating with verizon customers.

(Note, you have to click on the providers to see absolute magnitude -- the graphs are scaled to show relative outage over time within a given provider; order of 150k verizon vs 1.5k others)

At 2:14PM EST, Verizon said:

"Verizon engineering teams are continuing to address today's service interruptions. Our teams remain fully deployed and are focused on the issue. We understand the impact this has on your day and remain committed to resolving this as quickly as possible."

As someone responsible my whole career for uptime and network response, I really feel for the engineers, at the same time hoping my service comes back up soon. SOS

  • Odds are they have a ton of outsourced engineers who are an ocean away and unable to do anything.

    • That's very often the case. I bet there are frantic calls being made right now (probably using a competing carrier!) to Ericsson/etc to come to their rescue, which they happily will in exchange for a hefty fee.

I find this kind of odd. Yesterday, 2026-01-13, I - who lives in the greater Washington D.C. area - experienced A LOT of Verizon disruption. However, today, my service has been excellent. Maybe I'm from the future and don't know it. Did anybody else in my general area experience outages yesterday?

  • DC local. Total outage this afternoon. SOS on my phone for a few hours. Unable to log into my account.

  • Dallas metro here. I couldn't receive SMS based OTP from a bank for hours yesterday.

I've got a Verizon Network Extender and it appears to be online - the tunnel is up back to VZW's security gateway, but all of my phones are refusing to register to it.

I did manage to roam onto an international network on the boarder near me in New York/Canada, so some bits of the core seem functional for authentication.

When I roam internationally I appear to be on Telus's 3G network (no LTE) for data and voice is falling even further back it looks like.

  • I could see Verizon access points but just couldn't connect to any of them. I had no issue sending texts over wifi though.

    • Parts of the HLR might be unavailable or under a thundering herd as all phones are trying to register at once. The HLR would also be involved if using EAP-SIM/EAP-AKA so that would explain failures on the Wi-Fi access points.

My service was out for approximately 7 hours. But I pose a question that I've been wondering since:

I have a Moto. Updates are explicitly disabled. A lot of stuff has been deactivated via ADB. While Moto does try to force sneak updates against my settings and will, on occasion, I just so happened to grab my phone today and at approximately the very moment of the outage, noticed an unsolicited Moto update, which I cancelled. But at that moment, cellular was or went down (~1400) and remained so until ~2200.

Was this a coincidence, or could something much more interesting have happened, eg a serious security breach? An interesting coincidence, for me. I spent the day convinced that Moto sent a kill sig wanting me to buy a new phone.

  • Thanks a lot eth0up, we all went down waiting on you to accept that Moto update.

    • I have updates blocked, which is why the simultaneous update seemed odd.

      In my wild imagination, I vaguely surmised something involving compromise. I'm not sure what you're implying though, probably something spiteful.

Since this outage is still going on just a town away from their HQ... porting still works to get you going again on the same towers. You can get the device unlock pin from Verizon postpaid sent through a push message to the device so it doesn't rely on SMS.

Ironically I was planning to port my parents from Verizon to US Mobile to save them some money since they aren't financing any devices (there's a sale from them that ends today) and I've just done that on the first line and I now have service on that line with Verizon, where the remaining Verizon postpaid is still dead.

Some outlets reporting T-Mobile and ATT as well.

I assume state on state cyber attacks are commonplace but get minimized to avoid public fear.. perhaps this will be the first notable one.

It's also weird that some people here in the office on Verizon work fine, and others are on SOS. No correlation between phone versions or hardware that I could deduce. I also see the same on X: https://x.com/CPTholen/status/2011520566159982758

It came up for around 5-10 minutes at 15:00 EST, but is currently still down.

  • If they're on different phones, they could be on different bands, different towers, and different paths, one or more of which could be impacted by whatever the underlying problem is. iPhone vs Android would be the most blatant tell that something like this is at fault, but it could also be different configurations from different stores causing them to interact with the cellular network in different ways.

    Something like a routing configuration, BGP failure, or underlying network misconfiguration would cause seemingly bizarre results with some phones working and some not with no obvious correlation. Compare Access Point Names under Mobile Settings on android, and whatever the equivalent is on iPhones, and check things like whether 5G allowed and data roaming is enabled.

    If it's a cyber attack of some sort, then there's all sorts of different attack vectors that would cause these outcomes.

  • My wife and I are on the same Verizon family plan. One of us can be down while the other is fine, then 30 minutes later it's the opposite. It's been like that all day.

    • Same here, except that when here (central-western NJ) when someone "recovers" here we go from SOS to a few bars but no LTE or 5G indicator. Yikes.

i know alot are joking / sarcastic about its a cyber attack- that said, Wouldn't it make more sense that whenever there is a "cyber attack" its more likely it would only affect one provider? ie, each has to have different systems / security postures ect, such that a non-public vuln useful to attack Verizon would likely not be exploitable/exposed at AT&T (or vise versa)?

  • why are you saying that this is affecting more than one provider?

    • i'm not saying that, I was asking more of a general question, others were saying that multiple carriers were having issues (w the only proof being downdetector and their incorrectly scaled Y axis graphs)

Anyone still using SMS for 2FA codes, here is your official notice to change that ASAP.

I have two Verizon phones on very different networks and both have not been working well since Tuesday - anyone also having this? I kept restarting my phones, airplane mode on/off etc

West coast too, down in LA at same time (12 PM EST / 9 AM PST). I think they’re way way way underselling the # affected (“thousands” lol)

I was unable to receive SMS based OTP from my bank yesterday for a couple of hours... Wonder if it's related. Anyone else?

Our Comcast DNS keeps going in and out too, not clear if it is related or knock on effect or something else entirely.

Phone hasn’t had a connection for hours. 5G wireless home is fine. Upstate South Carolina.

I still received 23 telemarketing calls today on my Verizon phone in Maryland.

downdetector is showing a lot of down mobile networks & services

  • Yeah, this is notable. If true, every mobile carrier getting hit at the same time says "coordinated incident", from whatever source and for whatever purpose.

    Edit to say: my Verizon FioS and cell service are both working fine, no noticeable interruption at any point today.

    Second edit to say: never mind, downdetector's home page normalizes report spikes so 1k and 100k both look identical.

  • The down detector site has Verizon outage reports two order of magnitude bigger, so it doesn't seem like a cyber attack to me. ~60-160k vs ~1.5-1.8k

I had a Verizon outage Monday. I called my neighbor who also has Verizon; hers was out.

But hers came back on when she paid her bill, oops! So...

I went to their website, which said "You have a local outage! Click here to know more...". I clicked there, and it said "There are no outages in your area." OK, so we've established that Verizon's website doesn't know shit.

I started troubleshooting with a tech support person ("I am in ... New... Jersey" - sure you are...), and discovered my optical interface whatsit was hanging by its cables in my basement, mysteriously knocked off its wall bolts. This happened sometime in the last 10 days, so it's a smoking gun.

I called for a repairman, because obviously the fall damaged the fiber alignment...

... except it didn't. The tree limb across the street that broke the cable coming into my house did cause a problem.

So... Verizon outages are complicated, and despite all their technical know-how, they don't really know shit.

The US would never purposefully cut of it's own communications, right? What would be the tells if that would have happened? And what could the average citizen do to be able to communicate regardless? Might be useful to always have that knowledge around, even if it isn't a personal threat to yourself today.
