Quoting https://docs.aws.amazon.com/general/latest/gr/rande.html

"Some services, such as IAM, do not support Regions; therefore, their endpoints do not include a Region."

There was a partial outage maybe a month and a half ago where our typical AWS Console links didn't work but another region did. My understanding is that if that outage were in us-east-1 then making changes to IAM roles wouldn't have worked.

The original poster said that none of AWS services are in a single AZ, the quote you referenced says that IAMs do not support regions.

Your quote cd mean two things.

- that IAM services are hosted in one region (not one AZ)

And/Or

- that IAM is for the entire account not per region like other services (which is true)
