Sorry, I thought the details a not important for the list, because the problem 
is on the remote site.

Here they are:  

Our dns resolvers are unable to reach the authoritative name server for 
sgsstudentbostader.se.

[ambauen@id-kom-rz-dock-2-34 ~]$ dig +short +norec  @46.239.64.34

[ambauen@id-kom-rz-dock-2-34 ~]$ dig +short +norec  @46.239.64.98

;; connection timed out; no servers could be reached

Our resolvers are using 129.132.128.142 and 129.132.128.206 as query source 
address.
Our IP Network range is 129.132.0.0/16.

Some time it is difficult to ask the right questions ;-)

Where is your 'dig' output? Any sane operator would request and/or provide that.

jeroen@noc:~$ dig +short @ns1.sgsit.se. www.sgsstudentbostader.se. any
46.239.65.68

Put that in /etc/hosts for a short time and you can at least browse their site.

Of course if you can't reach their prefix (46.239.64.34/24) you are out of 
luck, and that would also explain why you can't resolve anything, some silly 
people still think it is smart to have all eggs in one basket^Wprefix.

(and if you would have provided the dig output and related traceroutes for 
destinations that could have been unreachable, you would have had your answer 
already what was wrong ;)

Typically those are not read or too heavily spammed causing them to be not read 
unfortunately.
