TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	48ms	122ms	504
7d	100%	100%	49ms	171ms	2880
30d	100%	100%	66ms	308ms	15972

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	167ms	189ms	68
7d	100%	100%	167ms	192ms	360
30d	99.80%	99.80%	168ms	187ms	1992

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%	143ms	157ms	52
7d	99.67%	138ms	218ms	300
30d	99.76%	140ms	168ms	1674

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

Per ICANN Spec 10, we test all delegated nameserver IPs independently.
