TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	19ms	92ms	112
7d	100%	100%	19ms	139ms	2480
30d	94.12%	94.12%	19ms	143ms	3354

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	274ms	335ms	12

30d	100%	100%	292ms	426ms	296

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%	38ms	102ms	4
7d	100%	37ms	109ms	134
30d	100%	38ms	108ms	210

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