Overview
- Microsoft reported Azure Front Door began failing around 16:00 UTC, citing an inadvertent configuration change as the trigger.
- Microsoft 365, Outlook, Teams, Xbox, Minecraft and other Azure-backed services were affected, with third parties such as Alaska Airlines, Vodafone, Heathrow and NatWest reporting problems.
- Downdetector tallied peak user reports of more than 18,000 for Azure and nearly 11,700 for Microsoft 365 before counts trended downward as fixes progressed.
- Mitigations included blocking further Azure Front Door changes, failing the Azure portal away from AFD, rerouting traffic and rolling back to a last‑known‑good configuration, with nodes being recovered and traffic directed through healthy paths.
- Microsoft reported initial signs of recovery but warned of intermittent impact and temporarily blocked customer configuration changes, as the incident drew comparisons to last week’s major AWS outage and complicated the Outer Worlds 2 Game Pass launch and the company’s earnings day.
