Amazon S3 server access logs now include source region information, specifying which AWS Region requests to your data originate from. This identifies applications that are making cross-region requests, helping you to optimize cost and performance.
Source region information automatically appears at the end of each server access log entry with no additional configuration. For example, if your application requests data from your us-east-1 bucket from us-west-2, the log entry shows “us-west-2” as the source region.
This feature will be available in all AWS Regions in the coming weeks at no additional cost. To learn more about S3 server access log format and best practices, visit the S3 User Guide.
