TLD SLA Compliance Metrics

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% 128ms 129ms 10
7d 96.70% 216ms 348ms 212
30d 97.62% 191ms 285ms 294

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.

Test With Your Computer

DNS

dig @a.hu hu. SOA +dnssec +nsid Query SOA with DNSSEC validation and NSID

ICANN SLA Requirements

Per ICANN Registry Agreement Specification 10:

DNS SLA UDP RTT ≤ 500ms for 95% of queries. Availability: 99% (max 432 min/month downtime).
WHOIS SLA RTT ≤ 4000ms for 95% of queries. Availability: 98% (max 864 min/month downtime).
