Between 6:44 AM and 9:12 AM PDT, customers experienced elevated latency and error rates in response to IAM API requests, as well as delays in describing recently created or modified IAM resources. In addition, between 6:44 AM and 10:02 AM, propagation of IAM API updates was delayed in the ME-SOUTH-1, EU-SOUTH-1, AP-EAST-1, and AF-SOUTH-1 regions, and newly created or recently updated IAM users, credentials, roles, and policies may not have been available for authentication and authorization in those regions. Other AWS Services that rely on IAM changes to provision resources, such as CloudFormation, were also impacted. Authentication and authorization for existing users, credentials, roles, policies were not impacted. The issue has been resolved and the service is operating normally.
