Microsoft Rules Out Cyberattack Behind Widespread Global Service Disruption

Microsoft has confirmed that it has found no evidence of malicious activity or a cyberattack behind the widespread outage affecting several of its services, including Outlook, Teams and Copilot.

The company's Executive Vice President, Charles Lamanna, said preliminary findings showed no signs of a cyberattack linked to the disruption, which began at around 16:00 GMT and affected users across multiple countries.

The outage disrupted government agencies and businesses in Australia, Japan and the United States. Downdetector reported service disruption complaints across 74 countries and territories within approximately one hour.

Microsoft said its latest recovery efforts had not delivered the expected results, adding that it was reviewing affected infrastructure and data traffic routes to improve service stability and restore normal operations.
