> Do you have one admin interface per region
This ^^^ When I go to login, it redirects me to: https://us-east-1.signin.aws.amazon.com
And for example the S3 console is on the URL https://console.aws.amazon.com/s3/home?region=us-east-1
Of course this doesn't mean I can't easily switch to a different region, or for that matter control all my regions from a single interface, but there is some distinction.
