TLD SLA Compliance Metrics
Spec 10DNS
| Period | Availability | RTT Compliance | RTT p50 | RTT p95 | Checks | TSLAC |
|---|---|---|---|---|---|---|
| 24h | 100% | 100% | 13ms | 202ms | 500 | |
| 7d | 99.59% | 99.59% | 12ms | 1559ms | 2700 | |
| 30d | 99.62% | 99.62% | 12ms | 1559ms | 14940 |
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% | 30ms | 33ms | 66 | |
| 7d | 100% | 28ms | 28ms | 360 | |
| 30d | 100% | 39ms | 40ms | 2004 |
Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.
