Catch DNS issues before they cascade
Atatus DNS monitoring validates resolution time, uptime, and record integrity from global probe locations. Catch nameserver outages, propagation delays, hijacking attempts, and expiring domains before they turn into cross-service outages.

Everything DNS your team should be watching
DNS outages are catastrophic — they take down every service at once. Atatus continuously validates every record from every region.
DNS Resolution Time Monitoring
Measure resolution latency from 15+ global locations. Alert on tail latency spikes that hint at nameserver issues before they fail outright.
DNS Uptime & Nameserver Health
Monitor each authoritative nameserver independently. Detect partial outages (3 of 4 NS responding) that most tools miss.
DNS Record Integrity
Validate A, AAAA, CNAME, MX, TXT, NS, SOA, and SRV records against expected values. Catch accidental changes or malicious hijacking.
DNSSEC Validation
Verify DNSSEC signatures and chain of trust. Alert on key rollovers, signature expiry, and validation failures.
DNS Propagation Tracking
After a DNS change, track propagation across resolvers globally. Confirm when a change is live everywhere versus when it's still stuck in a cache.
Domain Expiry & Registrar Alerts
Monitor domain expiry dates and registrar lock status. Prevent the extremely rare but extremely painful 'our domain expired' incident.
Why teams add Atatus DNS monitoring to their stack
DNS is the biggest single-point-of-failure most teams ignore
When DNS fails, every service fails — API, website, email, auth. Yet most teams have no DNS-specific monitoring until the first outage. Atatus continuously probes every nameserver, every record, from every region, with sub-minute detection.
Catch partial outages that happen more often than full ones
Full DNS outages are rare; partial outages (one nameserver flaky, one region cached stale, DNSSEC signature expired) are common. Atatus probes each authoritative NS independently and alerts on partial degradation that single-check tools miss entirely.
Correlate DNS failures with application impact
When a DNS failure occurs, Atatus ties it to the synthetic transactions that failed, the APM traces that timed out, and the Real User Monitoring sessions that saw browser errors. One UI, one timeline, one root cause.
No per-record pricing
Most DNS monitoring tools price per record or per domain. Atatus flat per-host pricing includes unlimited DNS monitoring alongside uptime, SSL, synthetic, and APM.
