.cyou SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	94ms	344ms	88
7d	100%	100%	93ms	233ms	476
30d	100%	100%	52ms	234ms	1616

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	414ms	632ms	24
7d	100%	100%	422ms	593ms	120
30d	99.75%	99.50%	424ms	726ms	404

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%	41ms	534ms	22
7d	100%	41ms	86ms	120
30d	100%	66ms	118ms	408

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