TLD SLA Compliance Metrics
Spec 10DNS
| Period | Availability | RTT Compliance | RTT p50 | RTT p95 | Checks | TSLAC |
|---|---|---|---|---|---|---|
| 24h | 100% | 100% | 47ms | 115ms | 30 | |
| 7d | 100% | 100% | 47ms | 188ms | 420 | |

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% | 131ms | 133ms | 8 | |
| 7d | 98.00% | 131ms | 312ms | 150 | |
| 30d | 98.67% | 131ms | 261ms | 226 |
Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.
