TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	12ms	144ms	312
7d	100%	100%	12ms	161ms	5616
30d	95.58%	95.58%	12ms	161ms	7340

WHOIS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	37ms	122ms	12
7d	100%	100%	38ms	102ms	212
30d	100%	100%	37ms	103ms	272

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	38ms	10
7d	100%	37ms	38ms	198
30d	100%	36ms	38ms	260

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