What DNS monitoring tracks

DNS monitoring checks resolution and reputation signals that can interrupt access even when the website and servers themselves are healthy.

DNS health

DNS record availability

Resolution failures

DNS blocklist status

Why it matters

DNS issues can masquerade as outages, reputation problems, or intermittent customer failures. Keeping DNS visible shortens investigations.

DNS issues can look like full outages

Blocklist problems can affect email and reputation
