Increased API Error Rates

4:01 AM PDT We are investigating increased API error rates in the AF-SOUTH-1 Region. Existing instances are unaffected.

4:21 AM PDT We are experiencing elevated API errors and latency with the IAM authentication service in the AF-SOUTH-1 Region. This is causing impact on services that require IAM authentication. We are actively investigating root cause to identify a path to mitigation.

5:13 AM PDT We continue to see elevated API and latency for IAM authentication and authorization requests in the AF-SOUTH-1 Region. The IAM errors affect any AWS API call that requires authentication, though some calls may still be succeeding due to API credential caching. We have all teams engaged in investigation of root cause and mitigation, but we do not have an ETA for recovery at this time.

5:28 AM PDT We are starting to see recovery of IAM authentication and authorization requests, and customers should be seeing improvements in API error rates in the AF-SOUTH-1 Region. We are continuing to monitor and work towards full recovery.

5:39 AM PDT We are continuing to see improvement in IAM authentication and authorization API error rates, and a subsequent improvement in AWS service API availability in the AF-SOUTH-1 Region. We continue to monitor this event closely, and will do so until all services have fully recovered.

6:22 AM PDT All service APIs are now operating correctly, and we continue to work towards full recovery of services in the AWS Management Console. We’re continuing to restore normal operations to all AWS consoles in the AF-SOUTH-1 Region.
