TLD SLA Compliance Metrics
Spec 10DNS
| Period | Availability | RTT Compliance | RTT p50 | RTT p95 | Checks | TSLAC |
|---|---|---|---|---|---|---|
| 24h | 100% | 100% | 111ms | 154ms | 396 | |
| 7d | 100% | 100% | 111ms | 217ms | 2160 | |

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 | 86.36% | 155ms | 1481ms | 22 | |
| 7d | 90.00% | 234ms | 1047ms | 120 | |
| 30d | 91.91% | 295ms | 801ms | 408 |
Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.
