TLD SLA Compliance Metrics

Spec 10

30d	98.80%	98.80%	72ms	191ms	2668

RDAP

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%	141ms	155ms	22
7d	92.59%	129ms	142ms	108
30d	98.64%	139ms	184ms	660

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