TLD SLA Compliance Metrics
Spec 10DNS

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% | 33ms | 33ms | 4 | |
| 7d | 98.51% | 35ms | 182ms | 134 | |
| 30d | 99.01% | 35ms | 143ms | 202 |
Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.
