TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	17ms	775ms	176
7d	100%	100%	12ms	27ms	960
30d	100%	100%	12ms	951ms	3240

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	300ms	313ms	48
7d	100%	99.58%	301ms	489ms	240
30d	93.69%	93.45%	345ms	1579ms	824

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%	36ms	40ms	44
7d	100%	36ms	51ms	240
30d	99.63%	36ms	87ms	820

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