DNS

DNS Health Score

Your DNS either resolves or it doesn't — but in between lies a grey area that gets expensive the day something breaks: a single nameserver, DNSSEC switched off, a TTL set far too short. Specula measures those in eight structural checks and reduces them to one score.

• Eight checks, one score

  Nameserver redundancy, DNSSEC, TTL values, apex configuration, MX and email authentication records become a score out of 100.

• A drop arrives with its reason

  The notification doesn't just say the score fell; it names the check that slipped.

• The threshold was measured, not guessed

  Notifications fire at a 5-point drop, and that number isn't arbitrary: the largest drop a transient query failure could cause was measured at 4 points. The threshold sits above it so it doesn't produce false alarms.
