I'm frustrated that AWS managed services are not moving away from this AZ. I'm seeing CloudFront returning a 504 trying to connect to API Gateway for a number of requests. After 2 hours you would think they would stop trying to route traffic there.

I don't quite understand this. Aren't the availability zones denoted by a letter?

My Aurora instances are in eu-west-2a/eu-west-2b/eu-west-2c, so what is euw2-az2?

The letters are different per-account.

thanks, first time seeing that

It's so the load is evenly distributed across AZs because I bet most people just select -az-1.

As another commenters mentioned, the AZ letter different per account.

“To identify the location of your resources relative to your accounts, you must use the AZ ID, which is a unique and consistent identifier for an Availability Zone. For example, use1-az1 is an AZ ID for the us-east-1 Region and it is the same location in every AWS account”

So each separate AWS account will have a different AZ name that maps to use1-az1, but use1-az1 is a region-wide constant.
