TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	61ms	142ms	198
7d	100%	100%	61ms	210ms	3888
30d	95.00%	95.00%	62ms	335ms	5160

WHOIS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	50.00%	25.00%	6055ms	10028ms	12
7d	49.39%	26.83%	5352ms	10109ms	164

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%	115ms	143ms	6
7d	98.05%	115ms	339ms	154
30d	98.61%	115ms	283ms	216

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