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	98.86%	155ms	383ms	88
7d	99.38%	151ms	289ms	480
30d	99.55%	152ms	232ms	2684

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