TLD SLA Compliance Metrics

Spec 10

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% 60ms 68ms 66
7d 100% 61ms 70ms 356
30d 100% 59ms 68ms 2002

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).
WHOIS SLA RTT ≤ 4000ms for 95% of queries. Availability: 98% (max 864 min/month downtime).
