This is so odd. I have two phones with AT&T currently sitting right next to each other. One has service, the other is in SOS mode.

Does it still show bars in SOS mode? Or is SOS just “I dunno can’t see no cell towers but maybe it’d work?”

I wonder if the MVNOs that piggyback on AT&T are showing down also. If not, it’s some AT&T service authorization system that exploded.

Some of our staff are reporting similar where their partner's phone has service and their's doesn't. Both on same AT&T family plan.

So the radio bands may play into it although I would think with latest iPhones, they can use any of the bands from AT&T although I could be wrong.

Reporting status externally is hard. I worked at a cloud provider and while we had very detailed metrics about how our systems were functioning, it was difficult to distill that information in a way that customers would understand if they were being impacted or not, and what the impact would be. Just reporting raw numbers wouldn’t give customers the context to understand what was actually going on.

How do you actually report, for example, that .003% of your customers are having a really bad day but the rest are just fine?

Earlier quoted context omitted.

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 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?

I prefer fully automated tests publicly revealed because the main thing I want to know (as a customer) is should I keep trying to fix my end or give up because GitHub exploded again.

It’s most annoying when you have something like recently - known maintenance work on my upstream home fiber connection that was resulting in service degradation (but not complete loss, my fiber line was back to DSL or dialup). The chat lady could see that my area was affected, but the issue lookup system couldn’t.

If the issue lookup had told me there as an issue I’d’ve gone on my merry way.

I even checked a few more times until it was resolved; the issue never appeared in the issue lookup system.

Aren't these exactly what p99 illustrates? Of course you'd have to have your use cases logged well enough to be able to aggregate the 99th percentile accurately to each customer flow

Mine says SOS Only, shows no bars.

Different bands could be affected differently if it is solar radiation related. Same exact model of phone?

Different models, in my case.
