IAM Identity Center multi region support - Resilience

Question

IAM Identity Center controls access to its permission sets and applications from its primary Region only. Does this mean if the primary region is down, Nobody will be able to sign in? or the services which are dependent on Identity Center for authorization will become unusable?

Is it possible to have a backup or secondary region for IAM Identity Center to mitigate such risks?

Hello.

As of September 2024, IAM Identity Center can only be configured for one region.

My prediction is that if a failure occurs in the region where IAM Identity Center is set up, you will not be able to sign in, although it will depend on the severity of the failure.  
Therefore, the IAM Identity Center documentation recommends having a way to sign in in case of an emergency.
