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

Impact statement: Starting at 20:30 UTC on 30 September 2026, customers using ExpressRoute and/or 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.

Current status: 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 paused the associated operating system servicing activity, preventing additional resources from entering the affected servicing workflow. Since taking this action, we are seeing mitigation progress across affected resources, …

Starting at 20:30 UTC on 30 September 2026, customers using gateway services may be experiencing degraded or interrupted network connectivity.

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.

Impact Statement: Starting at 10:00 UTC on 29 September 2026, a subset of customers using OpenAI Service, Foundry Agent Service, Foundry Models, and Cognitive Services, in Sweden Central may experience intermittent request failures, increased latency, and HTTP 5XX error codes when submitting requests to affected models and APIs hosted in this region.

Current Status:

Currently we are monitoring improvements in the overall experience. Initial findings indicate that a backend service which is relied on to retrieve metadata information when managing requests for this region, was experiencing timeouts when reading from dependent database and caching layers. As a result, requests that depend on …
