Azure outage, Oct 29, 2025

23 vendors posted 22 incidents between 16:00 and 22:00 UTC, against about 21 incidents from 17 vendors in the same hours on an ordinary week. 5 vendors named Azure in 5 incidents (5 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.
