TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	73ms	239ms	96
7d	100%	100%	72ms	1611ms	1728
30d	93.97%	93.97%	73ms	1611ms	2174

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	307ms	321ms	12
7d	100%	99.52%	313ms	429ms	208
30d	100%	98.97%	313ms	773ms	292

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%	116ms	157ms	16
7d	98.68%	115ms	282ms	228
30d	98.77%	114ms	273ms	326

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