AWS is not any better really on this. In fact 2 years ago (to the day!) we had a complete AZ outage in our local AWS region. This resulted in their control plane going nuts and being unable to shut down or start new instances. Then capacity problems.
That's happened several times, actually. That's probably just the latest one. The really fun one was when S3 went down in 2017 in Virginia. Caused global outages of multiple services because most services were housed out of Virginia and when EC2 and other services went offline due to dependency on S3, everything cascade failed across multiple regions (in terms of start/stop/delete...ie. api actions. Stuff that was running was, for the most part, still working in some places).
...I remember that day pretty well. It was a busy day.
