TLD SLA Compliance Monitoring

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 100% 102ms 102ms 22
7d 87.50% 89ms 715ms 96
30d 98.15% 78ms 209ms 648

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.

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).
