TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	29ms	43ms	352
7d	100%	100%	29ms	126ms	1884
30d	99.92%	99.92%	29ms	126ms	10512

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	410ms	442ms	64
7d	100%	99.15%	412ms	638ms	352
30d	100%	99.85%	411ms	480ms	1984

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%	59ms	78ms	88
7d	99.78%	60ms	121ms	464
30d	99.72%	67ms	129ms	2544

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