.tunes SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	38ms	145ms	576
7d	100%	100%	34ms	128ms	3120
30d	100%	100%	31ms	152ms	17288

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	388ms	502ms	44

30d	100%	99.93%	383ms	565ms	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	100%	37ms	104ms	54
7d	100%	40ms	105ms	300
30d	99.88%	39ms	123ms	1652

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