TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	6.0ms	14ms	264
7d	100%	100%	3.0ms	27ms	1440
30d	100%	100%	3.0ms	107ms	8130

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	77.27%	100%	86ms	97ms	44
7d	75.42%	100%	86ms	100ms	240
30d	75.45%	99.93%	86ms	99ms	1336

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%	31ms	32ms	88
7d	99.58%	32ms	78ms	480
30d	99.89%	32ms	49ms	2656

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