Microsoft says services fully restored after global outage

  • Microsoft restored 365 services on Saturday morning after a global outage that began Thursday evening, affecting millions of users across 74 countries including email and Microsoft Teams.
  • A technical issue from "a recent network change" during an earlier capacity upgrade caused the failure, though Microsoft emphasized the incident was "not related to cyber" attacks or artificial intelligence agents.
  • In Britain, the National Health Service and police enacted "robust contingency plans" to maintain operations, while Downdetector recorded more than 130,000 reports of Outlook-related problems at the peak.
  • Acknowledging the severity, Microsoft stated, "We are deeply sorry for the disruption this incident has caused our customers and partners," as engineers managed recovery gradually to process email backlogs.
  • Microsoft will publish a post-mortem "shortly" covering repair items to prevent future outages, as the incident highlights global dependence on one provider's digital infrastructure and ecosystem resilience concerns.
