Nameserver not resolving working domain

Hello,
I have a weird issue with a bind9 resolver: it fails to resolve a domainname
that appears to be absolutely correctly configured (and which works correctly
from another bind9 server). I even expect it to work after restarting Bind,
but I don't want to do it yet in sake of finding what is wrong.
The host I cannot resolve is www.intervocative.com, returning no answer.
The domain is delegated to ns19 + ns20.worldnic.com. Both are reachable. From
the nameserver:
ns:/usr/local/named-ns/var/log # dig @localhost www.intervocative.com
; <<>> DiG 9.3.2-P1 <<>> @localhost www.intervocative.com
; (2 servers found)
;; global options: printcmd
;; connection timed out; no servers could be reached
ns:/usr/local/named-ns/var/log # dig @ns19.worldnic.com www.intervocative.com
; <<>> DiG 9.3.2-P1 <<>> @ns19.worldnic.com www.intervocative.com
; (1 server found)
;; global options: printcmd

Where could this go wrong? Our firewall isn't logging anything. Everyone is
reachable, even through IPv6 (the only IPv6 addresses involved being those
for a + b.gtld-servers.net).
Any hint to what to try, before I have to restart bind, would be much
appreciated...
Best regards,
