Snowflake outage, Jun 30, 2021

6 vendors posted 6 incidents between 18:00 and 20:00 UTC, against about 5 incidents from 4 vendors in the same hours on an ordinary week. 2 vendors named Snowflake in 2 incidents (2 of them blamed it). Snowflake posted “Multiple Deployments: MI-20210630” at 18:28 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.
