TLD SLA Compliance Monitoring

TLD SLA Compliance Metrics

Spec 10

DNS

Period Availability RTT Compliance RTT p50 RTT p95 Checks TSLAC
24h 100% 100% 7.0ms 31ms 396

DNSSEC Validation Metrics

Registry Agreement Spec 6

DNSSEC 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% 35ms 36ms 66
7d 99.71% 34ms 64ms 344
30d 99.95% 35ms 41ms 1956

Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.
