We are investigating an alert for Azure ExpressRoute Gateway in multiple Azure regions. We will provide more information as it becomes available.

Starting at 20:30 UTC on 30 September 2026, customers using ExpressRoute and/or Azure VPN Gateway may experience degraded or interrupted connectivity. We are also seeing impact to components responsible for managing network gateways, which may affect some management operations. Our investigation has identified a correlation between the onset of impact and infrastructure ‘operating system’ servicing activity. During this activity, some network gateway instances became unhealthy or temporarily unavailable. We have observed different recovery behavior across the affected services. Many impacted ExpressRoute gateways are recovering as the servicing operation completes. However, some supporting management components have not recovered automatically, and we are actively working to restore those components. Our current working hypothesis is that infrastructure operating system servicing is triggering an unexpected condition in some network service instances. We have not yet confirmed the underlying failure mechanism and are continuing to investigate why affected instances became unhealthy and why recovery behavior differs between services. We have paused further operating system servicing associated with this activity to prevent new instances from entering the affected servicing workflow. In parallel, our engineering teams are restoring network management components that have not recovered automatically as well as evaluating additional recovery actions for resources that remain unhealthy. We are continuing to monitor recovery across the affected services and will provide additional information within the next 30 minutes or as events warrant.

Starting at 20:30 UTC on 30 September 2026, customers using ExpressRoute and/or VPN Gateway may experience degraded or interrupted network connectivity. Customers may also experience failures or delays when performing some network management operations. Current status: We have paused the infrastructure servicing activity associated with the onset of this event, preventing additional resources from entering the affected servicing workflow. We are seeing continued recovery across impacted ExpressRoute gateways and are monitoring this recovery to confirm that it remains durable. For VPN Gateway, some affected gateways have experienced reduced redundancy rather than a complete loss of connectivity. Recovery continues to be monitored. Some supporting network management components have not recovered automatically and are contributing to management operation failures in a subset of affected regions. Engineering teams are actively restoring these components using alternate healthy instances where available. Our investigation continues to show a correlation between this event and infrastructure operating system servicing activity. However, the underlying failure mechanism has not yet been confirmed. We are investigating why some network service instances became unhealthy and why recovery behavior has differed between services. We will provide additional information within the next 30 minutes, or sooner if events warrant.

We are investigating an issue affecting Azure OpenAI and Foundry agent services in the Sweden Central region. Impacted customers may experience intermittent errors when making service requests. We are investigating the underlying issue and exploring mitigation options to restore normal service performance. Our analysis remains ongoing, and we are closely monitoring service health while continuing our investigation. We will provide additional information as it becomes available.

We are investigating an issue affecting Azure OpenAI Service, Azure AI Foundry Agent Service, Azure AI Foundry Models, and Azure AI Cognitive Services in the Sweden Central region. Impacted customers may experience intermittent request failures, increased latency and HTTP 5XX error codes when making service requests. We are investigating the underlying issue and exploring mitigation options to restore normal service performance. Our analysis remains ongoing, and we are closely monitoring service health while continuing our investigation. We will provide additional information as it becomes available.
