TLD SLA Compliance Metrics

Spec 10

DNS

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
24h	50.00%	40ms	40ms	56
7d	50.00%	35ms	36ms	300
30d	50.00%	36ms	36ms	1678

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