Microsoft Azure is experiencing an outage affecting ExpressRoute and VPN Gateway connectivity across multiple regions. Engineering teams are currently working to restore network management components and monitor recovery progress.
Starting at 20:30 UTC on 30 September 2026, customers using ExpressRoute and VPN Gateway may have experienced degraded or interrupted network connectivity. Customers may also experience failures or delays with some network management operations. Current status: ExpressRoute gateways are showing significant recovery as of 22:35 UTC, and we continue to monitor service health to validate that recovery is sustained. We have paused infrastructure servicing activity associated with the onset of this event, preventing additional resources from entering the affected workflow. For VPN Gateway, some affected gateways experienced reduced redundancy or loss of connectivity, and recovery continues to be monitored. Some supporting network management components have not recovered automatically and continue to contribute to management operation failures in affected regions. Engineering teams are actively restoring these components using healthy instances where available. Our investigation has identified a correlation between the timing of this event and infrastructure operating system servicing activity. The underlying failure mechanism has not yet been confirmed, and we continue to investigate why some network service instances became unhealthy and why recovery behavior differed across services. We will provide additional information within the next 30 minutes, or sooner if events warrant.
