TLD SLA Compliance Metrics
Spec 10DNS
| Period | Availability | RTT Compliance | RTT p50 | RTT p95 | Checks | TSLAC |
|---|---|---|---|---|---|---|
| 24h | 100% | 100% | 110ms | 186ms | 792 | |
| 7d | 100% | 100% | 101ms | 227ms | 4248 | |
| 30d | 100% | 100% | 100ms | 907ms | 24096 |
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 | 0.00% | 133ms | 140ms | 56 | |
| 7d | 0.00% | 120ms | 191ms | 290 | |
| 30d | 0.00% | 138ms | 164ms | 1626 |
Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.
