TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	10ms	692ms	352
7d	95.65%	95.65%	11ms	621ms	1808
30d	99.25%	99.25%	10ms	1113ms	10608

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	299ms	307ms	48
7d	91.53%	91.53%	607ms	648ms	236

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%	35ms	36ms	22
7d	95.83%	35ms	201ms	96
30d	97.99%	36ms	194ms	648

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