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	97.37%	59ms	63ms	76
7d	100%	62ms	63ms	416
30d	99.91%	71ms	72ms	2314

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