AWS AmazonCloudWatch documentation change
Summary
Clarified Network Health Indicator (NHI) metric limitations for AWS Direct Connect attachments using Cloud WAN or Transit Gateway. Removed redundant explanations about intermediary routing impacts.
Security assessment
The changes improve accuracy of documentation about NHI metric limitations but do not address security controls or vulnerabilities. No security implications identified in the diff.
