TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	45ms	105ms	110
7d	100%	100%	45ms	108ms	600
30d	100%	100%	44ms	142ms	2025

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	85ms	767ms	24

30d	100%	100%	68ms	141ms	412

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%	62ms	63ms	44
7d	100%	62ms	63ms	240
30d	100%	58ms	59ms	812

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