TLD SLA Compliance Metrics

Spec 10

DNS

30d	100%	100%	28ms	174ms	10496

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	315ms	450ms	80

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%	37ms	102ms	54
7d	99.66%	37ms	102ms	290
30d	99.94%	38ms	102ms	1644

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