We are aware of an issue affecting Azure Data Factory in UK South, where a subset of customers may experience failures, delays, or timeouts when running pipelines and activities, managing integration runtimes, or performing authoring operations. Our engineers are actively investigating the cause and impact . Workaround: Customers are advised to cancel and retry affected pipeline or activity runs that fail, time out, or remain in progress longer than expected. Further updates will be provided as more information becomes available.

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

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.

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 these processes were delayed or failed intermittently. Queued requests are being processed. We are continuing to investigate the health of supporting platform infrastructure or system processes that may impact these requests. The next update will be provided within 60 minutes, or as events warrant.

We are investigating an issue affecting a subset of infrastructure within the East US region. Customers may experience service degradation for dependent Azure services. Our teams are actively investigating the cause and working to restore normal operations. More information will be provided as it becomes available.

We are investigating an issue impacting multiple Azure services in the West US regions. Engineering teams are actively assessing the scope and working to mitigate customer impact. Further updates will be shared as they become available

We are investigating an issue affecting a subset of infrastructure within the Southeast Asia region. Customers may experience connectivity issues or service degradation for dependent Azure services. Engineers are actively investigating the cause and working to restore normal operations. More information will be provided as it becomes available.

We have observed recovery for a portion of the infrastructure affected by this issue within the Southeast Asia region. While many impacted services and resources have recovered, a subset of customers may continue to experience connectivity issues or service degradation for dependent Azure services. Engineers are actively working to restore the remaining impacted infrastructure and validate full service recovery.More information will be provided as it becomes available.

We are aware of an issue affecting access to the Azure portal in the Australia regions. Our engineers are actively investigating the cause and impact. Further updates will be provided as more information becomes available.

We are investigating a networking issue affecting connectivity to Azure services in the West US region. Impacted customers may experience intermittent connectivity failures, increased latency, or difficulty accessing Azure services. Customers with traffic traversing the West US region may also experience downstream impact. We are exploring mitigation options on affected network devices. Early indications suggest the issue is related to network traffic flow through the impacted infrastructure; however our analysis remains ongoing. We are closely monitoring traffic while continuing our investigation. We will provide additional information as it becomes available.

We are investigating an issue affecting connectivity to Azure services for a subset of customers in the West US region. Impacted customers may experience intermittent issues when accessing Azure services.We will provide more information as it becomes available.

GitHub Enterprise Cloud with Data Residency is experiencing a service outage impacting all services, issue identified and mitigation in progress. For details please go here: : https://us.githubstatus.com/posts/details/PBJ0QTY

Impact Statement: Starting at 21:45 UTC on 15 June 2026, a subset of Azure customers leveraging services which depend upon MCR (Microsoft Container Registry) for storing images may experience 401 authentication errors for requests attempting to pull Microsoft images from mcr.microsoft.com.Current Status: We detected this issue via internal service monitoring upon identifying a spike of 401 errors. We’ve identified a potential underlying factor to be a recent update which introduced a code regression, and we've completed roll out of a hotfix to address the code regression and mitigate impact for affected customers. We are closely monitoring internal telemetry to validate full mitigation and prevent further occurrences. The next update will be provided within 60 minutes, or as events warrant.

We are actively investigating customer alerts of 401 authentication errors when pulling images from mcr.microsoft.com. We’ve identified a potential underlying factor related to a recent update made to a backed service and we are actively working on determining mitigation workstreams. More information will be provided shortly.

Impact Statement: Starting at 09:39 UTC on 29 May 2026, you have been identified as a subset of customers using Azure OpenAI service in multiple regions who may experience degraded request success where some requests returned errors or failed to complete. Current Status: We identified this issue through internal automated service monitoring after detecting a drop in call success rates. Our investigation indicates that the issue is linked to elevated server-side errors within a backend service layer in the affected region. We are actively investigating and working to determine the full scope and mitigation steps. The next update will be provided within 60 minutes, or sooner if there are significant developments.

Impact Statement- Starting at 04:27 UTC on 29 May 2026, customers may experience increased latency, intermittent connectivity, or timeouts when accessing resources hosted in the West US 2 region. Engineers are actively investigating the issue and working to restore network stability. Some requests may succeed upon retry as connectivity intermittently recovers. We are sending targeted communications to impacted customers through the Azure Service Health dashboard. The next update will be provided within 60 minutes.

Impact Statement- Starting at 04:27 UTC on 29 May 2026, customers may experience increased latency, intermittent connectivity, or timeouts when accessing resources hosted in the West US 2 region, due to a power event. We are in process of recovering power and working to restore infrastructure in the region. We started seeing partial recovery and will be sending targeted communications to impacted customers through the Azure Service Health dashboard. The next update will be provided within 60 minutes.
