TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	45ms	237ms	54
7d	100%	100%	45ms	285ms	1326
30d	94.44%	94.44%	45ms	285ms	1776

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	1037ms	1525ms	12
7d	100%	97.81%	1081ms	1773ms	228
30d	99.67%	97.70%	1090ms	1768ms	304

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	50.00%	251ms	5006ms	12
7d	45.87%	635ms	5015ms	218
30d	55.81%	522ms	4224ms	310

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