Microsoft restores all cloud services after global outage

20min.ch (German) —

Microsoft has fully restored all systems after a major outage affecting its cloud services, the company announced Saturday morning. The disruption impacted Outlook, Microsoft 365, Teams, and other services. The outage disrupted meeting planning, calendar functions, and temporarily affected the Copilot AI assistant and third-party interfaces like OpenAI and Anthropic. Microsoft confirmed the cause was an internal network capacity upgrade issue, not a cyberattack or AI-related activity. The company also stated the outage was unrelated to the technical failure causing thousands of US flight cancellations since Friday evening. Microsoft had reported gradual progress resolving the issue on Friday afternoon.
