AWS returned ServiceUnavailable because the server was temporarily unable to handle the request.

ServiceUnavailablegeneral

Observed message

ServiceUnavailable

Why it happens

  • The target AWS service is temporarily unavailable.
  • The service is under transient load or undergoing a brief internal issue.
  • The request reached a temporary server-side failure path.

How to fix it

  1. Retry the request with exponential backoff.
  2. Check AWS service health if the issue affects many requests.
  3. Reduce burst traffic if retries are amplifying the outage.
