We have identified the root cause for increased error rates and latency of Connect, Subscribe and Publish operations for new connections in the US-WEST-2 Region and are working towards resolution. A scheduled update to optimize the underlying infrastructure for the AWS IoT registry resulted in lower memory availability than required – this has been corrected, and recovery is in progress. Existing connections are not affected.
Between 11:12 AM and 11:45 AM PDT, we experienced elevated API errors and latencies and connectivity issues in the EU-NORTH-1 Region. The issue has been resolved and the services are operating normally.
