TLD SLA Compliance Metrics
Spec 10DNS
| Period | Availability | RTT Compliance | RTT p50 | RTT p95 | Checks | TSLAC |
|---|---|---|---|---|---|---|
| 24h | 100% | 100% | 159ms | 196ms | 30 | |
| 7d | 100% | 100% | 159ms | 222ms | 1120 | |

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 | 50.00% | 229ms | 229ms | 2 | |
| 7d | 46.25% | 579ms | 579ms | 160 | |
| 30d | 45.34% | 650ms | 650ms | 236 |
Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.
