TLD SLA Compliance Metrics

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 50.00% 37ms 37ms 20
7d 50.00% 37ms 37ms 120
30d 50.00% 37ms 37ms 406

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).
