DNSSEC Validation Metrics
Registry Agreement Spec 6DNSSEC 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 | 100% | 119ms | 124ms | 8 | |
| 7d | 100% | 121ms | 125ms | 212 | |
| 30d | 98.29% | 121ms | 298ms | 292 |
Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.
