Evidence to review

  • Response logs, maintenance configuration, incident timeline and recovery checks.

How to implement

  1. Monitor server errors, timeouts and crawl-heavy paths.
  2. For temporary overload, use appropriate documented responses and Retry-After where justified.
  3. Do not leave intended public pages in prolonged failure or mass noindex states.
  4. Test recovery, caching and alert thresholds before an emergency.
