Azure west us outage, Jul 23, 2026

25 vendors posted 25 incidents between 14:00 and 23:00 UTC, against about 38 incidents from 26 vendors in the same hours on an ordinary week. 5 vendors named Azure in 5 incidents (3 of them blamed it). Vendors reported an Azure outage; Azure’s own incident for this date is not in the archive.

Observed, not verified. A line means a vendor’s incident named another vendor, or started in the same window. It is not a proven cause.

Times are UTC; lags are from when the first vendor named Azure.
