Microsoft outage disrupts Outlook and Teams for users in 74 countries
Microsoft reported outages affecting Outlook and Teams services globally on Thursday, November 13, impacting tens of thousands of users across 74 countries and regions, with the disruption lasting over five hours. The company attributed the failure to increased load on infrastructure in several regions, not traffic growth, and redirected data flows to alternative routes, leading to gradual recovery. Issues also affected the Copilot AI assistant, and Microsoft acknowledged potential connection problems for Microsoft 365 users in other regions. The outage impacted other firms, including AI companies OpenAI and Anthropic, and electric truck maker Workhorse Group postponed its quarterly earnings report to November 16 due to software problems.
