TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	46ms	230ms	396
7d	99.57%	99.57%	46ms	242ms	2112
30d	99.92%	99.92%	47ms	1707ms	11988

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	90.91%	79.55%	1458ms	4948ms	44
7d	95.76%	85.59%	1323ms	4159ms	236
30d	96.74%	90.99%	1196ms	3167ms	1288

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	95.45%	66ms	890ms	88
7d	97.44%	65ms	651ms	468
30d	97.77%	66ms	640ms	2554

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