TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	125ms	175ms	176
7d	100%	100%	131ms	151ms	960
30d	100%	100%	132ms	170ms	5348

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	423ms	445ms	44
7d	100%	100%	424ms	448ms	240
30d	100%	100%	426ms	451ms	1324

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%	153ms	161ms	52
7d	100%	154ms	161ms	240
30d	100%	154ms	175ms	1396

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