SERVFAIL is the generic error message.
There are lots of things that can cause a SERVFAIL. Bad
delegations, bad responses to EDNS queries, the servers
not being authoritative, firewalls blocking queries /
replies and lastly code bugs.
This is not a exhaustive list of things. It a matter of
eliminating things one by one until you find the fault.
