TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	42ms	90ms	176
7d	100%	100%	50ms	171ms	960
30d	100%	100%	53ms	171ms	3240

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	108ms	166ms	40
7d	100%	100%	97ms	191ms	240
30d	100%	100%	100ms	163ms	816

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%	55ms	181ms	44
7d	100%	71ms	162ms	240
30d	99.88%	128ms	184ms	812

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