TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	38ms	122ms	48
7d	99.53%	99.53%	38ms	194ms	1266
30d	94.28%	94.28%	39ms	307ms	1717

RDAP

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%	115ms	139ms	4
7d	98.64%	116ms	277ms	220
30d	97.72%	150ms	333ms	307

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