TLD SLA Compliance Monitoring

TLD SLA Compliance Metrics

Spec 10

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 Status
24h 50.00% 38ms 39ms 88
7d 50.00% 35ms 36ms 480
30d 49.96% 36ms 36ms 2670

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