DNSSEC Validation Metrics

Registry Agreement Spec 6

DNSSEC is required by the Registry Agreement (Specification 6) but is not part of the Spec 10 SLA. We monitor DNSSEC validation independently.

Period Validation Rate RTT p50 RTT p95 Checks Status
24h 100% 35ms 39ms 22
7d 91.53% 33ms 431ms 118
30d 98.36% 36ms 124ms 670

Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.

Per ICANN Spec 10, we test all delegated nameserver IPs independently.
