TLD SLA Compliance Metrics
Spec 10DNS
| Period | Availability | RTT Compliance | RTT p50 | RTT p95 | Checks | TSLAC |
|---|---|---|---|---|---|---|
| 24h | 100% | 100% | 69ms | 167ms | 1056 | |
| 7d | 100% | 100% | 70ms | 205ms | 5760 | |
| 30d | 100% | 100% | 71ms | 1154ms | 31968 |
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% | 134ms | 138ms | 66 | |
| 7d | 100% | 135ms | 142ms | 360 | |
| 30d | 99.75% | 134ms | 162ms | 1992 |
Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.
