-Starting in early 2025, in AWS Regions that are [enabled by default](https://docs.aws.amazon.com/accounts/latest/reference/manage-acct-regions.html), AWS STS requests to the global endpoint (`https://sts.amazonaws.com`) will be automatically served in the same AWS Region as your workloads. These changes will be gradually deployed by mid-2025. These changes will not be deployed to opt-in Regions. We recommend that you use the appropriate AWS STS regional endpoints.
