This. Same timeframe and I've lived through both lots of lightning storms and in areas with lots of power failures. Some of them intermittent and essentially caused by transformers blowing up. Like earlier this winter, we had multiple storms where you'd hear a transformer blow up, in many cases even seeing the sky light up as well from it, power going out, couple seconds, power coming back, next transformer blowing out, rinse, repeat.

On the other hand I've read about plenty of stories of the "cheap" UPSs you'd usually buy as a consumer (not to name any brands coz I've never had any) actually causing such issues in the first place. Without any actual surges from the grid.

That said, being totally not superstitious (for real, but someone's gonna "kill me" if they find out I wrote this and something dies from a surge...), now I guess I need to knock on wood like seventeen times ...

I do use surge protectors when we're on generator power temporarily.

Not only should you get rid of them, but also they are a fire hazard.

Also, do not accidentally plug surge protectors into each other, metal oxide varistors can star fires _without_ meaningful surge conditions when you do so.

I prefer to buy products without MOVs entirely due to the risk, with the exception of one, Tripp Lite Isobars; but I prefer to use series mode protectors such as Brickwall or SurgeX.

When I lived in Costa Rica, I lost three surge protectors in a year to power surges. During one such power surge, I didn't notice that the red light indicating surge protection was already out, and a power surge fried my (knockoff) Macbook power adapter, leaving me without a way to work for a day.

Not too bad, just rural. We used to lose stuff every 10 years or so.

One day The Big One came along and fried nearly everything. "Once burned, twice shy."

Hopefully someone can learn from my mistake and not have to do it post-mortem.

Heavy industry can also cause these kinds of power surges to happen.

Last year an aluminum smelter in Iceland had a transformer blow which caused a big power surge on parts of the very well developed national power grid. The surge caused damage to electronics in some households and companies near to the smelter.

If your close neighbours have surge protectors then you benefit little from installing your own.

>Admittedly: financial protection, not data protection

You should have data backups regardless, because there are plenty of ways to lose data that don't involve power surges.

Have they ever paid out on one of those, or is it like CAs who offer liability protection for their certificates carefully set up in such a way that they never have to pay out.

The California bay area, at least all the sides of it I’ve lived on. We currently have a whole house battery, whole house surge protector, a second surge protector, and a UPS between the router/nas/etc and PG&E.

It’s not good enough. At least the power stays on once the grid stops bouncing (or once I manage to log into the rebooting battery gateway computer to have it flip the “off grid” breaker, or go outside and flip the manual one by the meter).

Areas with lots of thunderstorms. Also more rural areas with long power lines with few taps off for customers — the long runs are both exposed to many nearby strikes and accept induction well, and the few customers are fewer power sinks to dissipate the spike. So, you're more likely to get hit, and hit harder.

Open aerial wiring can shortcircuit two phases, bringing a low impedance surge that can damage most electric and electronic equipment.

I have lived in the DC metro area inside the beltway or in Sillicon Valley my entire adult life and have only had above ground power wiring. Despite tree ordnances and wind storms and a grid so aged if we see lightning we lose power.

> Lightning damage is mostly an issue if the last-mile power lines are above ground.

So 99.99999% of the world.
