FAQ

Common questions

Why three resolvers?

A change can reach one public resolver before another. Comparing three shows you a propagation problem or an unexpected change before your users hit it.

Which record types are supported?

A, AAAA, CNAME, MX, TXT, NS and CAA. See the DNS monitoring docs for details.
