Power Outage at Microsoft Data Center Microsoft has confirmed that a significant power outage at one of its West US data centers triggered widespread service disruptions yesterday, leaving thousands of Windows 11 users unable to access the Microsoft Store or complete Windows Updates. Even with strong redundancy measures, the incident, which started early on Saturday morning, shows how vulnerable centralized cloud infrastructure can be. On February 7, 2026, the disruption started at around 8:00 UTC.

When trying to download apps or retrieve important operating system patches, users in various regions—but particularly those using Azure services hosted in the West US region—started to report timeouts and failures.

Microsoft acknowledged the underlying cause in an official statement issued soon after the incident was reported: "A datacenter power outage is affecting customers' ability to finish tasks in the Microsoft Store and Windows Update." Because of this, some users might encounter errors or timeouts when downloading Windows updates or installing apps from the Microsoft Store. Impact of Azure storage clusters The backend failure was linked to a facility's loss of utility power, but the immediate consumer impact was felt on Windows 11 desktops.

The outage had a cascading effect on Azure storage clusters, which support the content delivery networks for the Store and Update services, according to Microsoft's initial post-incident report.

"An unplanned utility power outage at one of our West US datacenters earlier today caused some areas of the facility to lose power," the company said in a status update. "Power has since stabilized throughout the impacted areas after backup power systems were automatically activated." However, complicated cloud environments are not immediately restored by merely turning on the electricity again.

It takes a long time for storage services to "cold start" and for data to re-synchronize across nodes. Users were still seeing error messages long after the server room lights were turned back on, which can be explained by this latency. Microsoft cautioned that "service recovery is still in progress even though power has been restored."

"Storage services are slowly coming back online, and while recovery is complete, some customer impact may persist." In addition to not being able to download Candy Crush or the most recent security definitions, enterprise administrators also had to deal with observability issues. The telemetry pipelines that IT workers use to keep an eye on their own Azure resources were weakened by the power outage.

Customers may encounter "intermittent service unavailability or delays in monitoring and log data for some resources hosted in the affected datacenter areas," according to the impact statement. As the monitoring infrastructure caught up with the backlog of data, DevOps teams that depend on real-time logs to keep an eye on the health of their applications were left in the dark for several hours.

Microsoft states that it is "actively working to restore full service reliability" as of Sunday morning, February 8. As storage arrays finish their consistency checks, some residual latency is anticipated in the West US region, even though the majority of services have returned online. The solution for regular users who are experiencing Error 0x80070002 or other comparable timeout codes in Windows Update right now is straightforward: patience.

The company suggested that impacted customers try the Microsoft Store and Windows Update later.
