Amazon S3 Adds Source Region to Server Access Logs
🔍 Amazon S3 server access logs now include the AWS source region for each request, indicating the Region where a request originated. This information appears automatically at the end of every log entry (for example, a request to a us-east-1 bucket from us-west-2 will show "us-west-2") and requires no configuration or additional cost. The update helps teams identify cross-region traffic to optimize performance and cost and will roll out to all Regions in the coming weeks.
