Impact statement: As early as 19:46 UTC on 2 February 2026, we became aware of an issue causing customers to receive error notifications when performing service management operations - such as create, delete, update, scaling, start, stop - for Virtual Machines (VMs) affecting multiple regions. These issues are also impacting services with dependencies on these service management operations - including Azure Arc Enabled Servers, Azure Batch, Azure Cache for Redis, Azure Container Apps, Azure DevOps (ADO), Azure Kubernetes Service (AKS), Azure Backup, Azure Load Testing, Azure Firewall, Azure Search, Azure Virtual Machine Scale Sets (VMSS), GitHub (see https://www.githubstatus.com)..

Current status: We determined that these issues were caused by a recent configuration change that affected public access to certain Microsoft‑managed storage accounts, used to host extension packages. We have applied our mitigation across all impacted regions and have performed validation checks to ensure that all affected resources have had their configurations updated. At this stage, customers should see signs of recovery across regions. We are currently monitoring downstream services for any further impact. Our next update will be provided by 08:00 UTC, approximately 2 hours from now, or sooner if we have progress to share.

Impact Statement: Starting at 23:54 UTC on 26 September 2025, customers in Switzerland North may experience service unavailability or degraded performances for resources hosted in the region. Virtual Machines may have shutdown to preserve data integrity. 

Current Status: We were alerted to this issue by our telemetry informing us in a significant drop in traffic. It was discovered that a recent deployment introduced a malformed prefix in one of the certificates used for connection authorization. We have pinpointed the deployment error involving the certificate prefix and are rolling back the faulty deployment to restore normal traffic flow and service availability.

Majority of the impacted services have been fully recovered, and a subset are nearing completion. We continue to monitor traffic and service stability to ensure full recovery.
