TLD SLA Compliance Metrics
Spec 10DNS
| Period | Availability | RTT Compliance | RTT p50 | RTT p95 | Checks | TSLAC |
|---|---|---|---|---|---|---|
| 24h | 100% | 100% | 115ms | 242ms | 220 | |
| 7d | 98.33% | 98.33% | 116ms | 301ms | 1200 | |
| 30d | 99.51% | 99.51% | 116ms | 604ms | 4050 |
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% | 141ms | 143ms | 34 | |
| 7d | 100% | 141ms | 144ms | 180 | |
| 30d | 100% | 142ms | 152ms | 608 |
Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.
