A regional outage impacted Microsoft 365 and Copilot services in Japan and China due to a critical routing misconfiguration that isolated healthy infrastructure, causing intermittent login failures, app loading errors, and degraded performance across Outlook, Teams, OneDrive, and Copilot; Microsoft rebalanced traffic to restore availability, reported no security breach or data loss, and provided status updates while full recovery was confirmed as pending.
