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% 38ms 105ms 44
7d 100% 38ms 103ms 240
30d 99.75% 38ms 149ms 816

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