As far as I know, the attacks happened at different times. If Amazon knew that they had lost some data redundancy, shouldn’t they have been quickly mirroring that out of the region?

That would be a legal nightmare. They don't necessarily know what customers' data residency requirements are.
replyThis. We have (well, had) customers running in me-south-1 and once the first AZ went down we wanted to proactively move their data to other regions even just as cold backups. But our legal department slapped that down pretty quickly.
replyMost likely, their own data residency terms prohibit this. It would be interesting to know if, when 2 out of 3 AZs got destroyed, customers got a heads up to move their data to a different region?
replyWe received repeated, constant heads up to move our data by the first AZ much less second. The problem is that nobody is storing data in Bahrain unless there are data residency requirements for it.
replynobody wakes up one morning and chooses to launch instances, CDN or S3 and would choose Bahrain as that without a requirement to, we were contractually and legally forbidden (in the middle as a vendor) to copy even encrypted data where we don't have the key out for redundancy, so the best we could do was tell our subcustomers to download all of their buckets to their office or some employee laptops at their office
AZs weren’t meant to be disaster resistant, eg, an earthquake or hurricane could take out a whole region.
replyRegions were always the scale of disaster isolation on AWS.
Regions are really the scale of disaster isolation only in extreme cases - such as global catastrophe (meteor strike taking out a city) or in this case, when actively targeted in war. I don't really see the same thing happening to a US or European region.
