TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	50ms	204ms	147
7d	100%	100%	48ms	181ms	798
30d	99.92%	99.92%	48ms	184ms	4395

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	1038ms	1103ms	44
7d	99.58%	99.17%	1055ms	1278ms	240

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%	117ms	164ms	66
7d	99.71%	114ms	194ms	348
30d	99.35%	114ms	233ms	2000

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