I haven't had service since around 3am this morning, my internet (fixed wireless) was also down around that time but has since come back on. I had just assumed it was local tower maintenance until I woke up and see it's still out and it's effecting millions. But was surprised to see it barely mentioned/getting engagement here given the scale.

This reminds me of the recent discussion on status pages. https://news.ycombinator.com/item?id=39099980 They need to be accurate. At&t status claims everything is fine. My wireless service is down. Down detector has tens of thousands of reports, so clearly everything is not fine.

Status pages are basically useless if they’re public facing.

Either they automatically update based on automatic tests (like some of the Internet backbone health tests) or they’re manually updated.

If they’re automatic, they’re almost always internal and not public. If they’re manual, they’re almost always delayed and not updated until after the outage is posted to HN anyway.

Which status page?

Which is better? How do you know whether an issue is individual to a customer or a quick blip that will resolve in a few seconds?

NOAA is reporting R3 activity. Solar flare outage seems likely

There was an earth directed X class, but not a big one. If that could affect SS7 I would expect it to also take out a chunk of the internet but I am not seeing that. [1] There are many cellular networks having issues but some could be and likely are resellers of others. [2] Probably more likely SS7 related as marcus0x62 mentioned. Another potentially SS7 related possibility? [3]
