Microsoft 365 and Azure experienced a major global outage on 23 July caused by a bug in automated network maintenance that incorrectly removed IP routes from multiple network devices in the West US region. The incident disrupted SharePoint, Teams, OneDrive, Power Automate, and other cloud services for thousands of users.

This Wire brief sits within Fusion42's coverage of Enterprise Software, and 5 sources have reported it between 24 Jul 2026 and 25 Jul 2026.

◆ The Wire takeaway

If you build on Azure or Microsoft 365, an automation bug just took your platform offline for hours—and Microsoft's own maintenance tool did it. You now have a hard dependency on a system that can fail catastrophically without human review; talk to your infrastructure team this week about failover patterns that don't rely on a single cloud region's automation layer.
