I have only observed this with this mallorcazeitung domain so far. 
Perhaps it has something to do with my server or the network environment 
of my server host. I have another identical server, but in a different 
network / on a different host system. And on the second server, the 
duration of the uncached query for this domain is normal (128 msec).

Problem server 1
;; Query time: 3348 msec

Server 2
;; Query time: 128 msec

I restarted server 1, but this did not bring any improvement. But so far 
it only takes so long with this mallorcazeitung domain.

I tried to activate logging (found it on a website), but the first 
attempt resulted in an error. I'm a bit too exhausted now, as I've been 
sitting in front of the PC all week and now need to take a break.


mkdir /var/log/named
chown bind:root /var/log/named
chmod 0750 /var/log/named

nano /etc/bind/named.conf.local

logging {
     channel my_syslog {
         syslog daemon;
         severity notice;
     };
     channel my_file {
         file "/var/log/named/messages";
         severity info;
         print-time yes;
     };

     category default { my_file; };
}
