.fun SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks

7d	0.00%	0.00%	—	—	1440
30d	4.33%	4.33%	14ms	45ms	8168

RDAP

24h	50.00%	100%	402ms	466ms	40

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	0.00%	5001ms	5004ms	84
7d	0.00%	5001ms	5003ms	480
30d	0.00%	5001ms	5004ms	2648

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