Microsoft is struggling to fix access to its services after a tech outage left people around the world without access.
Apps including Outlook, Teams, Sharepoint, Word, Excel and PowerPoint were affected, as well as AI assistant Copilot.
A Microsoft spokesperson said there was “no indication of a cyber-attack” as users were denied access to some of these services for several hours on Thursday and into Friday.
The tech giant said some of its servers were not performing as expected after an update. It has tried multiple approaches to bring back the services, including rolling back updates and limiting traffic to the affected servers.
However they became unavailable again once traffic returned.
In its latest update, posted on X, Microsoft stated: “We’ve monitored the status of the changes applied to improve serviceability and confirmed they’re not taking as expected.
“We’re identifying alternate workstreams that can be applied to increase capacity in the face of sustained traffic management imbalances.”
Microsoft’s executive vice-president of Copilot, Charles Lamanna, said on X: “We regret that today’s outages caused disruptions for our customers, and we are working to address the issue.
“We will continue to share more information as soon as we have it, and for now I can confirm that there is no indication this is the result of malicious or cyber activity.”
