We are beginning to see improvements as we continue to work towards recovery for the AWS IAM CreateRole and CreateServiceLinkedRole API Error Rates. Full resolution is estimated to take a few hours. Other AWS services such as AWS CloudFormation whose features require these actions will continue to be impacted. User authentications and authorizations are not impacted.
Between 12:40 PM and 1:07 PM PST, we experienced elevated API errors and event delivery latencies in the US-WEST-2 Region. The issue has been resolved and the service is operating normally.
