TLD SLA Compliance Metrics
Spec 10DNS
| Period | Availability | RTT Compliance | RTT p50 | RTT p95 | Checks | TSLAC |
|---|---|---|---|---|---|---|
| 24h | 100% | 100% | 89ms | 141ms | 48 | |
| 7d | 100% | 100% | 89ms | 146ms | 1014 | |

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 | 50.00% | 159ms | 159ms | 8 | |
| 7d | 50.00% | 159ms | 159ms | 180 | |
| 30d | 50.19% | 160ms | 160ms | 263 |
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.
