.ht SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	46ms	564ms	66
7d	92.44%	92.44%	35ms	120ms	357
30d	98.65%	98.65%	49ms	272ms	2007

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	50.00%	50.00%	461ms	8425ms	48
7d	43.10%	43.10%	1850ms	10008ms	232
30d	47.60%	47.60%	1134ms	10006ms	1336

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	0.00%	65ms	95ms	22
7d	0.00%	63ms	420ms	120
30d	0.00%	70ms	202ms	668

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

ICANN SLA Requirements

Per ICANN Registry Agreement Specification 10:

DNS SLA UDP RTT ≤ 500ms for 95% of queries. Availability: 99% (max 432 min/month downtime).

RDAP SLA RTT ≤ 4000ms for 95% of queries. Availability: 98% (max 864 min/month downtime).
