-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. For more information, see [AWS STS global endpoint changes](./id_credentials_temp_region-endpoints.html#reference_sts_global_endpoint_changes).
+In Regions that are [enabled by default](https://docs.aws.amazon.com/accounts/latest/reference/manage-acct-regions.html), requests to the AWS STS global endpoint are automatically served in the same Region where the request originates. In opt-in Regions, requests to the AWS STS global endpoint are served by a single AWS Region, US East (N. Virginia). You can use a Regional AWS STS endpoint to reduce latency or provide additional redundancy for your applications.
