How this page decides

Proven, not inferred

Once a day we send a real message to every active receiving domain from an external provider and confirm it arrives through the full path. With no recent evidence, delivery is reported as unknown rather than green.

Incidents record themselves

An incident is written automatically when a receiving domain degrades, recovers, or is taken out of rotation. Nobody edits this page by hand.
