TLD SLA Compliance Metrics
Spec 10DNS
| Period | Availability | RTT Compliance | RTT p50 | RTT p95 | Checks | TSLAC |
|---|---|---|---|---|---|---|
| 24h | 100% | 100% | 132ms | 227ms | 217 | |
| 7d | 81.63% | 81.63% | 111ms | 682ms | 511 | |
| 30d | 82.00% | 82.00% | 118ms | 682ms | 525 |
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% | 130ms | 131ms | 44 | |
| 7d | 91.53% | 118ms | 545ms | 236 | |
| 30d | 98.21% | 127ms | 248ms | 1340 |
Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.

Per ICANN Spec 10, we test all delegated nameserver IPs independently.
