US-B Service Degradation

We are investigating an issue affecting customers on our US-B infrastructure. The following services are currently impacted: Administration Console access, Directory Sync, Sync & Recover, and Remediation for Azure connections. API-based protection customers on US-B may also experience delays in message processing and remediation, which means threats could temporarily remain in Microsoft 365 inboxes. We will provide updates as more information becomes available. We apologize for the disruption.
