AWS general documentation change

Service: general · 2025-06-07 · Documentation low

File: general/latest/gr/cfn.md

Summary

Added Asia Pacific (Taipei) region endpoint and clarified throttle rate limits by adding 'per second' unit to all API operation rate limits

Security assessment

The changes add a new regional endpoint and improve documentation clarity by explicitly stating rate limits as 'per second'. While rate limits help prevent abuse, there is no evidence this change addresses a specific security vulnerability or incident. The update appears to be routine documentation improvement rather than security-related.
