Microsoft's West US Azure region experienced a five-hour outage when IP routes were accidentally removed from networking equipment, affecting all traffic entering or leaving the region but not services running entirely within it.

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 run multi-region on Azure to dodge single-region risk, you just saw it doesn't work—the routing layer between regions failed. You need a backup region on a different cloud provider.
