I have tons of this kind of data due to my side project, StatusGator. For some services like the big cloud providers I have data going back 7 years.

There indeed has been an uptick in AWS outages recently. You can see a bit of the history here: https://statusgator.com/services/amazon-web-services

(I was idly curious. It appears this data is available as part of the ~US$280/mo tier, along with a bunch of other things.)

I don't know about AWS, but both Google Cloud and Oracle Cloud maintain at least a high level history of past outages. See https://status.cloud.google.com/summary and https://ocistatus.oraclecloud.com/history

Given the hilariously awful reputation of the AWS status page I would hazard a guess that such a page would also be incredibly inaccurate.

If you can’t even admit you’re having an issue how can you keep an accurate record?

Similar with GCP. We had a pretty bad outage once where the status page was showing all green. Google informed us that because the actual issue was further down the stack and didn't trigger any internal SLOs the status didn't get an update. It took them hours to acknowledge and fix it.

Assuming you have a support contract the rep should send out a post-mortem page.

This is what happens when we've been affected by outages (even without involving support).

I think they did eventually but it took us quite a bit of troubleshooting, then creating a P1 ticket, then their investigation in order to get to the bottom of it and getting it fixed. And the status page never got an update, which is the subject I was adding to.

I'd say three times in as many weeks, give it or take

This is a little more broad, beyond just cloud infra providers, but includes some of the kind of data you're looking for (post-mortems for outage events): https://github.com/danluu/post-mortems
