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.

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 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.

Impact: From 08:40 UTC, 27 May 2026, some customers using Azure Synapse Analytics (private link, East US) may experience delays or failures accessing Synapse Studio or workspaces. We detected elevated connection failures via automated monitoring and are actively investigating.

Impact: From 08:40 UTC, 27 May 2026, some customers using Azure Synapse Analytics (private link) may experience delays or failures accessing Synapse Studio or workspaces across multiple regions. As of now mitigation is in progress, and we are seeing initial signs of recovery.
