Microsoft has announced that it is working to resolve connectivity issues after users across several countries reported disruptions to its services on Thursday.
The outage affected several of the company’s products, including Microsoft Teams, Outlook and its artificial intelligence platform, Copilot.
The technology company said part of its infrastructure was experiencing unusually high system loads, which it believed was contributing to the connection problems.
Although the disruption was initially reported in the United States, Microsoft warned that users in other regions could also experience difficulties accessing its services.
At about 18:30 GMT on Thursday, outage monitoring platform Downdetector recorded a surge in reports from users in the United Kingdom experiencing problems with Microsoft products.
In the United States, the platform had received more than 131,000 reports of issues with Microsoft Outlook by 18:15 GMT.
In a statement, Microsoft explained that the increased system load was not caused by a surge in user traffic but by the unexpected unavailability of several servers, placing additional pressure on the remaining infrastructure.
In a subsequent update issued at 19:50 GMT, the company said it was testing a new configuration in an effort to restore normal operations.
Microsoft explained that the issue was causing some servers to fail automated health checks, resulting in their unavailability.
