TLD SLA Compliance Metrics
Spec 10DNS
| Period | Availability | RTT Compliance | RTT p50 | RTT p95 | Checks | TSLAC |
|---|---|---|---|---|---|---|
| 24h | 88.89% | 88.89% | 59ms | 122ms | 108 | |
| 7d | 100% | 100% | 60ms | 207ms | 2580 | |
| 30d | 95.59% | 95.59% | 60ms | 540ms | 3414 |
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% | 45ms | 51ms | 10 | |
| 7d | 99.46% | 48ms | 115ms | 184 | |
| 30d | 98.11% | 48ms | 237ms | 264 |
Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.
