What the incident records say

Recorded starts in the same 30-day window, excluding maintenance. Vendors report incidents differently; fewer posts don’t prove better reliability.

Duration uses at least 5 incidents with vendor-supplied starts and recorded closure times. First-observed starts are excluded. A record may close when a post disappears or our tracking period expires; this does not confirm recovery. A missing closure time does not mean an outage is ongoing.
