11:30 am PT update: Microsoft Store and Windows Update services have been restored. Some IT administrators may continue to experience residual latency affecting Windows Server update operations, including the Windows Server sync API. This Server‑specific issue is being addressed separately. If you experience this latency, please contact Microsoft Support for business.


8:34 am PT post: A power outage at a datacenter is impacting customers' ability to complete operations in the Microsoft Store and Windows Update. As a result, some users may experience failures or timeouts when installing or updating Microsoft Store apps, or when downloading Windows updates.


Although power has been restored, service recovery is still in progress. Storage services are gradually returning online, and some customer impact may continue while recovery completes.


Microsoft is actively working to restore full-service reliability. Customers who are affected are advised to retry Microsoft Store and Windows Update operations later. We will provide more information as it becomes available.
