TLD SLA Compliance Metrics

Spec 10

DNS

24h	100%	100%	10ms	21ms	40

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	100%	36ms	39ms	2
7d	100%	38ms	40ms	166
30d	100%	37ms	40ms	238

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