Issue with Azure clusters with KeyVault enabled

This incident has been resolved.

Infrastructure rollback has completed and affected Azure clusters are recovering. The previously suggested firewall update is no longer necessary.

We are rolling back an infrastructure change that should allow Azure clusters with KeyVault to recover but affected customers can restore access more quickly by updating their KeyVault firewall with the latest Atlas control plane IP addresses: https://www.mongodb.com/docs/atlas/setup-cluster-security/#allow-access-to-or-from-the-service-control-plane

The issue has been identified and a fix is being implemented.

We are currently investigating an issue affecting Azure clusters with KeyVault enabled.
