Microsoft is working to restore services following a global disruption.
Microsoft reports progress restarting affected systems but warns that some services could become unresponsive again as traffic increases.
A Microsoft global outage disrupted connectivity across Teams, Outlook and Copilot on November 13, prompting urgent recovery efforts. The company said the disruption affected its apps and services across multiple regions.
In its latest update on X, Microsoft reported encouraging results from efforts to restart affected systems. Its teams were also monitoring those systems as work continued to restore services.
However, Microsoft had earlier warned that some services could stop responding again as traffic increased. Messaging and online meetings remained largely functional, the company said, despite the wider connectivity problems.
Microsoft global outage linked to server strain
Microsoft attributed the disruption to excessive demand on its infrastructure across several regions. However, it said an increase in traffic had not triggered the problem.
Instead, several servers unexpectedly became unavailable, leaving the remaining infrastructure to handle more work. Those servers process requests for workplace tools and other applications.
The company later said a key component of the affected servers was struggling with the workload. This added to the disruption as Microsoft continued investigating the cause and working on recovery.
Meanwhile, Microsoft executive Charles Lamanna ruled out a cybersecurity incident, saying neither hacking nor malicious activity caused the outage. In a post on X, he expressed regret over the disruption to customers and said Microsoft was working to address it.
