AWS availability zones are randomly shuffled for each AWS account – your us-east-2a won't (necessarily) be the same as another user's (or even another account in the same organization): https://docs.aws.amazon.com/ram/latest/userguide/working-wit...

You'll need to see which availability zone ID (e.g., use2-az3) corresponds to each zone in your account: https://aws.amazon.com/premiumsupport/knowledge-center/vpc-m...

edit: AWS identified this as a power loss in a single zone, use2-az1.

I wonder if this is done because people have a tendency or something to always create resources in 'A' (or some other AZ) and this helps spread things around.

And if I would have read the page the link points to better, that's exactly the reason
