Massive Microsoft Outage Hits Users Worldwide
13 Nov
Summary
- Microsoft services faced a massive global outage on Thursday.
- Internal server failure, not a cyberattack, is suspected.
- The disruption affected users in Israel and Asia-Pacific.
A significant global outage disrupted Microsoft's services on Thursday, affecting users across the world, including in Israel. Thousands reported issues connecting to essential platforms like Outlook, Microsoft 365, and Teams.
Initial assessments by experts suggest an internal server failure, not a cyberattack, caused the widespread disruption. The problem is believed to have originated when some servers failed a health check, leading to a domino effect as user traffic was redirected to other servers globally.
The outage extended to the Asia-Pacific region by Friday. This incident follows a smaller-scale outage in January and recalls a major Amazon Web Services disruption in October 2025, which was also attributed to internal errors.
Experts emphasize that the lack of DDoS indicators and no hacker group claiming responsibility further support the theory of an internal issue. Microsoft is expected to identify the specific server that initiated the cascading failure.
