Compare MX and TXT answers from independent public DNS resolvers.
Compare independent resolver answers
This check compares MX and TXT answers from Google Public DNS and Cloudflare 1.1.1.1. Differences usually mean cached answers have not converged or one resolver is temporarily unavailable.
Frequently asked questions
How long should propagation take?
It depends on the previous TTL and resolver cache; it may take minutes or hours.
Does this test every location?
No. It compares two independent public resolvers and should be treated as a practical signal, not a global proof.
