That is really strange. According to the nameserver check from the dutch internet domain registry, the dns settings are ok. Using different lookup nameservers from different locations and providers do give me back the correct ip address for this domain. By the way, the DNS server for this domain is not on this server and functions correctly for a couple of hundred other domains.
I get a directory listing in my browser for this domain with the following items:
is a symlink on the server to web3. web3 contains 1 file: index.php which is not parsed by php.
It seems to me that the documentroot setting is somehow messed up and is one level too high. However, even if this is the case, php still should work, which it doesn't
