FYI, yesterday DH updated the apache server. It's new configuration could make your Joomla site inoperable. All of my joomla sites started showing an "Internal Server Error 500" message.
The solution is to edit your .htaccess file and comment out the line that contains: "options +FollowSymLinks", i.e. put a "#" in front of it.
Luckily this was an easy fix. The problem is that the DH support folks had no idea what was going on and were unable to diagnose the problem which left me with about 4 hours of downtime. That sucked.
