TLD SLA Compliance Metrics
Spec 10DNS
| Period | Availability | RTT Compliance | RTT p50 | RTT p95 | Checks | TSLAC |
|---|---|---|---|---|---|---|
| 24h | 100% | 100% | 180ms | 307ms | 154 | |
| 7d | 98.84% | 98.84% | 181ms | 503ms | 1892 | |
| 30d | 93.93% | 93.93% | 182ms | 503ms | 2600 |
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% | 251ms | 319ms | 10 | |
| 7d | 94.64% | 252ms | 817ms | 224 | |
| 30d | 92.11% | 252ms | 1086ms | 304 |
Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.
