GitHub outage, Apr 21, 2020

10 vendors posted 9 incidents between 14:00 on Apr 21 and 02:00 on Apr 22 UTC, against about 13 incidents from 10 vendors in the same hours on an ordinary week. 4 vendors named GitHub in 3 incidents (4 of them blamed it). GitHub posted “Incident on 2020-04-21 15:45 UTC” at 15:45 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 GitHub posted (15:45).

Vendors that named GitHub

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