AWS general documentation change
Summary
Updated CloudFormation API throttle rate limits for the ap-southeast-6 region, reducing most limits to 2 requests per second (from 10, 20, or 0.5 in other regions) for operations like DescribeStackEvents, DescribeStackResource, ListStacks, and others.
Security assessment
This change documents rate limiting adjustments for a specific region (ap-southeast-6), which is a standard operational update for new region deployments. Rate limiting is a security control that helps prevent API abuse and denial-of-service attacks by restricting request frequency. However, there is no evidence in the diff that this change addresses a specific security vulnerability or incident; it appears to be routine documentation of regional service limits.
