It is calling http://software.msgpluslive.net/getip.php
, which is normally replying with the IP of the caller (<?php echo $_SERVER['REMOTE_ADDR']; ?>). As the DNS servers of msgpluslive.net are still down, that will fail and result in a timeout.
The server of msgpluslive.net is running, but it is not serving the correct website. You can test this by not using the DNS server, but adding this line to your C:\WINDOWS\system32\drivers\etc\hosts:
Then call the URL in your browser and you will get a website with title "Messenger Plus! has moved" and a meta refresh to patchou.com.
