TLD SLA Compliance Metrics

Spec 10

DNS

7d	100%	100%	36ms	451ms	1491
30d	95.88%	95.88%	32ms	451ms	2071

RDAP

24h	100%	100%	328ms	460ms	4

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%	82ms	85ms	10
7d	96.30%	82ms	438ms	216
30d	95.45%	82ms	517ms	308

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