DNS and SSL Health

DNS and SSL Health (/domains/health) scores one domain's DNS and certificate configuration and says what to fix.

Each check produces a finding with a severity — critical, warning or info — and a state: pass, fail, warn or skip. Failed and warned findings come with the remedy. The run is summarised as a score and a grade.

A run asks public resolvers for a dozen records, and every record that does not exist costs a full timeout, so a domain with no mail records at all is the slow case — and the one most in need of the answer. Give it up to a couple of minutes.
