Microsoft experienced a significant outage on Thursday that affected its cloud services globally. The issue started in the US and the Americas but quickly spread worldwide, impacting the company's services, including Outlook email and Teams video conferencing. Engineers struggled to recover downed servers, and the outage developed into a full-blown meltdown, affecting consumer and business email, files, and documents.
The outage also affected Microsoft's Copilot AI tools, Defender security screening software, and Intune dashboards. Some users experienced issues accessing their cloud-based Windows computers. Microsoft attributed the outage to a large number of servers being unexpectedly unavailable but has not disclosed the cause. The company continues to investigate and has stated that there is no evidence of malicious activity associated with the incident.
The outage had a broad impact across various industries, including TechCrunch's own email.
