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 0.00% 66ms 69ms 14
7d 0.00% 106ms 569ms 220
30d 0.00% 94ms 555ms 306

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

ICANN SLA Requirements

Per ICANN Registry Agreement Specification 10:

DNS SLA UDP RTT ≤ 500ms for 95% of queries. Availability: 99% (max 432 min/month downtime).
RDAP SLA RTT ≤ 4000ms for 95% of queries. Availability: 98% (max 864 min/month downtime).
