TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	19ms	92ms	112
7d	100%	100%	19ms	142ms	1808
30d	93.41%	93.41%	19ms	590ms	2518

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	274ms	309ms	4

30d	100%	100%	285ms	547ms	144

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	8
7d	100%	37ms	109ms	108
30d	100%	37ms	107ms	156

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