Microsoft Outlook, Teams, Copilot recovering after global outage lasting over 24 hours
Microsoft apologized for the disruption, which hit government agencies in Australia, Japan, and the US, and said it was a technical issue, not a cyberattack.
Microsoft's consumer services, including Outlook, Teams, and Copilot, have fully recovered after a global outage that lasted over 24 hours, disrupting online communications for businesses and governments. Microsoft expressed deep regret for the disruption, acknowledging the trust customers and partners place in their services. The company took responsibility for the incident, stating that it was conducted through technical challenges and failure modes, including cascading failures and thundering herds at their network perimeter.
Microsoft's executive vice president of Copilot, Agents, and Platform, Charles Lamanna, confirmed that there was no indication of a cyberattack or AI tooling issue causing the outage. The company began restoring services gradually due to the scale of demand, checking stability at each stage. Microsoft has pledged to publish a full post-incident report once their review is complete, detailing the step-by-step timeline and repair items to prevent similar outages in the future.
