Hi,
Here is a google translated answer from my host:
Hi Louis,
Excuse the long response time, Thomas is on vacation.
Can you get him (that is you teitbite) to perceive the problem to ping the domain?
He should open a command prompt and type "ping
www.fritidsmagasinet.dk" ... The expected answer is "86.48.90.169"
Everything seems to be properly set up here, so it's very strange that he can get another page served than the rest of us look ... I'm not sure whether it's our server he sees, but if it is then there is something wrong.
Sincerely. Internet 123 support - Mikkel
