.case SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	26ms	38ms	64
7d	100%	100%	26ms	56ms	1712
30d	96.00%	96.00%	24ms	101ms	2274

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	392ms	419ms	4
7d	100%	100%	400ms	423ms	212
30d	100%	100%	402ms	430ms	300

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%	53ms	54ms	12
7d	100%	52ms	55ms	314
30d	98.83%	49ms	80ms	427

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