What this measures: the share of our own availability checks that came back with a definitive answer. Nobody else publishes this, because nobody else is running bulk registry lookups at this scale and recording what came back.
What it does not measure: a registry’s uptime or quality. A low rate here can just as easily mean our requests are being rate-limited as it can mean anything about the registry itself.
These are current-state figures, not a history. We keep one record per domain, holding its most recent check — so a TLD that failed hundreds of times and then recovered reads as healthy here. A low rate means checks are failing now; a high one does not mean they always have.
Figures count domains checked, not queries — a domain checked six times counts once. Candidates we generated but never checked are excluded entirely; they are not failures. Snapshot rebuilt 2026-09-27 02:19:47.
