AWS outage, Jul 16, 2026

26 vendors posted 24 incidents between 08:00 and 22:00 UTC, against about 57 incidents from 35 vendors in the same hours on an ordinary week. 4 vendors named AWS in 4 incidents (3 of them blamed it), and 2 did so before AWS’s own status page. AWS posted “Increased 5xx Errors (global)” at 08:44 UTC.

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 AWS posted (08:44).

Vendors that named AWS

In their own words. “Blames” means a causal phrase sits next to the name (“due to”, “upstream provider”…).

Second hop: vendors that named another vendor

These incidents name a vendor other than AWS, for example a messaging or CDN provider that was itself affected.

Same window, did not name anyone

19 incidents started during the event without naming AWS or another vendor. Some are part of it, some are a normal day’s background (about 57 in these hours).
