There are 3 basic ways in which you might see an IAM/Identity related issue: 1. Control plane problems - these will manifest as latency or errors when calling the IAM service itself to make updates/additions/deletions of users/roles/policies/groups/etc. This is the most likely scenario if the dashboard names "IAM" specifically as the issue. 2. Propagation problems - problems with propagation will manifest as delays in seeing your control plane (IAM) actions reflected in the dataplane. For example, if you remove a user, but the user is still able to authenticate to AWS services for a lengthy period of time. 3. Dataplane problems - this will be problems with authentication or authorization to any and all AWS services. A widespread problem with authentication is less likely, but extremely bad, and will probably not be categorized in the dashboard as a problem only with IAM, since "IAM" is technically the name of the control plane.
