TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	34ms	117ms	96
7d	100%	100%	34ms	1466ms	2028
30d	95.22%	95.22%	35ms	1466ms	2656

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	93.75%	93.75%	352ms	2777ms	16

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%	130ms	134ms	12
7d	100%	131ms	138ms	170
30d	100%	131ms	137ms	228

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