Microsoft says services fully restored after hourslong global outage
Microsoft has confirmed that its core cloud applications have been fully restored following a global technical failure that disrupted workplace communications in more than 70 countries for approximately 24 hours. Exchange Online mailbox failures began shortly before 1:00 p.m. EST (18:00 GMT) on Thursday, followed by warnings that the instability had spread to Microsoft 365.
The issue was attributed to a problem during an earlier network capacity upgrade, with no signs of cyberattacks or rogue AI agents. Engineers restored partial server capacity by 4:00 p.m. EST (21:00 GMT) on Thursday using alternative service health checks and automated recovery tools. Services gradually improved through Friday, with recovery progress noted across various regions, though full restoration took until the following Friday.
Microsoft apologized for the disruption, emphasizing its commitment to customer trust and promising a comprehensive post-incident review. The outage affected public administration, transit, and healthcare networks worldwide, with notable consequences in the United States, Britain, Canada, and the Asia-Pacific region. Small businesses and individuals also experienced significant interruptions.
