TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	72ms	123ms	108
7d	93.28%	93.28%	67ms	167ms	596
30d	98.80%	98.80%	71ms	191ms	3340

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	101ms	174ms	32
7d	88.00%	88.00%	82ms	904ms	200
30d	59.97%	98.16%	40ms	212ms	1304

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%	140ms	154ms	22
7d	93.10%	131ms	143ms	116
30d	98.65%	139ms	183ms	666

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