.fail SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	69ms	163ms	462
7d	100%	100%	69ms	179ms	2484
30d	100%	100%	70ms	181ms	14064

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	94ms	117ms	72
7d	99.70%	99.70%	97ms	118ms	328
30d	99.95%	99.95%	98ms	134ms	1968

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	95.45%	130ms	147ms	44
7d	100%	140ms	156ms	236
30d	99.18%	142ms	250ms	1340

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