TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	187ms	263ms	63
7d	92.37%	92.37%	173ms	385ms	354
30d	98.51%	98.51%	185ms	385ms	2010

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	90.00%	90.00%	732ms	1325ms	20
7d	81.03%	81.03%	1325ms	1889ms	116

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%	43ms	248ms	44
7d	91.33%	41ms	384ms	196
30d	98.30%	55ms	297ms	1294

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