DNS 2 SERVFAIL vs 10 NOTZONE
Both DNS 2 (SERVFAIL) and 10 (NOTZONE) belong to the DNS Response Codes (RCODEs) category. 2 indicates that server failure. The name server encountered an internal error while processing the query. Meanwhile, 10 means that name not contained in zone. A name used in the Prerequisite or Update section is not within the zone denoted by the Zone section.

Server failure. The name server encountered an internal error while processing the query.
Gördüğünüzde
The recursive resolver could not get an authoritative answer — commonly caused by DNSSEC validation failures, unreachable upstream nameservers, or misconfigured zones.
Nasıl Düzeltilir
Try a different resolver (e.g., 8.8.8.8 or 1.1.1.1) to isolate the issue. If you control the zone, check DNSSEC signatures, SOA serial consistency, and nameserver reachability.
