.mls SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	18ms	34ms	264
7d	100%	100%	18ms	79ms	1388
30d	100%	100%	18ms	89ms	7836

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	44ms	59ms	88

30d	100%	100%	46ms	68ms	2656

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%	28ms	28ms	44
7d	100%	28ms	28ms	232
30d	100%	28ms	36ms	1330

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