TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks

7d	100%	100%	7.0ms	325ms	2880
30d	100%	100%	5.0ms	343ms	16020

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	77.78%	100%	84ms	95ms	72

30d	75.90%	100%	87ms	116ms	2564

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%	31ms	31ms	44
7d	100%	32ms	35ms	240
30d	99.85%	32ms	33ms	1316

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