Between 2:02 PM and 2:23 PM PDT we experienced increased error rates and latencies for IAM operations in all AWS Regions. Attempts to create, describe, modify or delete IAM accounts and roles may have experienced a failure during this time. Authentication using IAM accounts and roles was not affected. The issue has been resolved and the service is operating normally.
We are investigating increased API error rates and latencies in the US-WEST-2 Region
