Overview
- Microsoft's cloud services, which began failing Thursday around 16:00 GMT, knocked out core apps including Outlook, Teams and Copilot and generated user reports from roughly 70 to 74 countries.
- By Friday Microsoft reported full restoration of access and said it had processed the backlog of Microsoft 365 email deliveries, posting step‑by‑step recovery updates on its service‑status page and on X.
- Microsoft attributed the outage to a technical fault tied to a previous network‑capacity upgrade and denied any link to a cyberattack or to AI-agent malfunction, a view relayed publicly by Australian officials.
- The outage disrupted real operations: Immigration New Zealand paused visa processing, Unity Health Toronto declared a 'code grey' and many organisations reverted to manual workarounds during the downtime.
- Experts warned the incident highlights the risks of heavy reliance on a small number of cloud providers, a concentration that can spread routine upgrade errors into broad public and commercial disruptions.
