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% 19ms 245ms 22
7d 100% 19ms 29ms 288
30d 100% 20ms 29ms 404

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.
