Servers we query for .mx
Public registry infrastructure — a whois, a
dig NS mx, and one read of
IANA’s bootstrap file
return the same three values. Listed here for convenience.
- WHOIS host
-
whois.mx - Authoritative nameservers
-
e.mx-ns.mx189.201.244.1i.mx-ns.mx207.248.68.1m.mx-ns.mx200.94.176.1o.mx-ns.mx200.23.1.1x.mx-ns.mx201.131.252.1c.mx-ns.mx192.100.224.1 - RDAP endpoint
- no RDAP server — .mx is checked by DNS / WHOIS
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.
