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	100%	43ms	234ms	44
7d	96.49%	42ms	308ms	228
30d	99.10%	50ms	333ms	1328

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