TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	48ms	123ms	141
7d	100%	100%	48ms	166ms	786
30d	99.92%	99.92%	48ms	255ms	4176

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	941ms	1106ms	44
7d	100%	99.57%	945ms	1240ms	232

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%	114ms	141ms	60
7d	99.17%	119ms	320ms	360
30d	98.70%	118ms	324ms	2006

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