TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	46ms	229ms	396
7d	100%	100%	46ms	244ms	2124
30d	99.92%	99.92%	47ms	1689ms	11874

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	97.06%	79.41%	1100ms	4920ms	68
7d	96.07%	87.92%	1228ms	4697ms	356
30d	96.47%	91.45%	1162ms	3817ms	2012

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	46.97%	669ms	5001ms	66
7d	47.74%	541ms	5001ms	354
30d	47.51%	622ms	5001ms	1968

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