Increased Error Rates

10:13 AM PDT We are investigating increased error rates and latencies for API Gateway in the EU-WEST-1 Region. Some other AWS services are also affected by this issue, which we will provide further details on shortly. We are working to determine root cause and resolve the issues.

10:31 AM PDT We can confirm increased error rates and latencies for API Gateway in the EU-WEST-1 Region. Both the error rates and latencies are at a low enough level where retries would allow for a request to succeed. We have identified the root cause and are working to fully resolve the issue. The following AWS services are experiencing low levels of error rates as a result of this issue: Amazon Certificate Manager (ACM), AppSync, Cognito, EKS, Fault Injection Simulator (FIS), Service Catalog, and Sagemaker. We continue to work towards resolving the issue.
