AWS AmazonRDS documentation change

Service: AmazonRDS · 2026-07-01 · Documentation low

File: AmazonRDS/latest/AuroraUserGuide/UsingWithRDS.IAMDBAuth.Troubleshooting.md

Security assessment

The change removes a specific rate limit number but retains the throttling error behavior and mitigation advice. No security vulnerability is indicated; this appears to be a documentation refinement.
