My feeling is this is an AWS issue. Our services hosted in AWS are not working either.

Do you have more info like services, regions etc? I see all green checks on the AWS Status page.

I'm sure you know this already, but that status page isn't worth the cycles on your CPU, you would be better served asking the toaster if AWS is functioning properly than checking that status page.

These events seem to be happening almost on a monthly basis now. IRC was never this unreliable and at least with netsplits it was obvious what had happened because you'd see the clients disconnect. IME messages just fail to send with Slack, then you can retry but they're not properly idempotent and you end up sending the messages twice. It's really poor.

I have also been having intermittent issues with Twitter also this morning (can't load tweets etc) and was wondering if it was connected.

This is definitely going to catalyze a nascent move over to Discord for my team. (~80 person consulting agency, distributed)

That's it, I'll move from [closed source, centralized, paid service] to [closed source, centralized, paid service]!

When I was at Uber, we noticed that most incidents are directly caused by human actions that modify the state of the system. Therefore, a large "backlog" of human actions that modify the system state have a much higher chance of causing an incident. My bet is that this incident is caused by a big release after a post-holiday "code freeze".

I would bet it's just the influx of traffic post holiday with systems that haven't been updated in so long maybe some annoying memory leaks have crept up and gone unnoticed or some other bad state that was exacerbated by return to work day for most NA folks. Code freezes were good at identifying bugs that only show up after long periods.

Doubt anyone releasing big changes Monday morning.

Of course, yeah, but at least you can sometimes see a yellow and infer it really means red :/.

Downdetector indicates a possible correlation between Slack issues and AWS reports, eventhough Slack peaks at 13960 problems and AWS at 111:

Zoom as well, no? Beautiful to see the whole team grinding to a halt. Or maybe everybody finally is getting some time for deep focused work.
