A major Microsoft outage on November 12 disrupted MS365, Outlook, Teams, and AI integration services from OpenAI and Anthropic, causing significant service interruptions globally including in South Korea. Microsoft halted deployments, redirected traffic, and is working on recovery while investigating the cause and deeming a hacking attack unlikely.

This Wire brief sits within Fusion42's coverage of Enterprise Software, and 56 sources have reported it between 12 Nov 2026 and 13 Nov 2026.

◆ ◆ The Wire takeaway

Microsoft's outage exposes your dependency on MS services and AI connectors. You need to test backup workflows and minimise reliance on single cloud vendors before your operations stall.
