TLD SLA Compliance Metrics

Spec 10

DNS

30d	99.75%	99.75%	56ms	170ms	1624

RDAP

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%	56ms	160ms	22
7d	100%	108ms	156ms	120
30d	100%	138ms	156ms	408

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