.smart SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	29ms	60ms	292
7d	100%	100%	28ms	45ms	1680
30d	99.93%	99.93%	28ms	53ms	9352

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	401ms	426ms	36
7d	100%	100%	404ms	433ms	172
30d	100%	100%	406ms	444ms	940

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%	53ms	58ms	30
7d	100%	52ms	58ms	204
30d	100%	53ms	57ms	1144

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