The default region for global services including https://console.aws.amazon.com is us-east-1, but there are usual regional alternatives. For example: https://us-west-2.console.aws.amazon.com

It would probably be clearer that they exist if the console redirected to the regional URL when you switched regions.

STS, S3, etc have regional endpoints too that have continued to work when us-east-1 has been broken in the past and the various AWS clients can be configured to use them, which they also sadly don't tend to do by default.
