TLD SLA Compliance Metrics
Spec 10DNS
| Period | Availability | RTT Compliance | RTT p50 | RTT p95 | Checks | TSLAC |
|---|---|---|---|---|---|---|
| 24h | 100% | 100% | 120ms | 217ms | 150 | |
| 7d | 100% | 100% | 108ms | 193ms | 810 | |
| 30d | 99.10% | 99.10% | 85ms | 193ms | 4497 |
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% | 121ms | 193ms | 66 | |
| 7d | 99.72% | 124ms | 207ms | 360 | |
| 30d | 99.45% | 105ms | 158ms | 1988 |
Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.
