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
24h	100%	152ms	158ms	88
7d	99.38%	152ms	247ms	480
30d	99.70%	153ms	220ms	2688

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