.tui SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	30ms	60ms	176
7d	100%	100%	29ms	47ms	960
30d	99.77%	99.77%	28ms	92ms	5332

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	406ms	451ms	44
7d	100%	100%	402ms	446ms	240
30d	100%	99.92%	404ms	474ms	1332

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%	55ms	60ms	78
7d	100%	53ms	58ms	420
30d	99.83%	53ms	65ms	2292

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