.ht SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	68ms	739ms	141
7d	100%	100%	53ms	666ms	810
30d	100%	100%	36ms	848ms	4482

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	50.00%	50.00%	788ms	10004ms	68
7d	50.00%	50.00%	704ms	10006ms	360
30d	48.05%	48.20%	1090ms	10006ms	2000

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%	101ms	175ms	52
7d	0.00%	106ms	200ms	300
30d	0.00%	83ms	132ms	1662

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).
