Hi folks,
Well, I've been @ work all day, so not watching the server too closely... but I just loaded up our web page and noticed the DM server had crashed.
I have remote desktopped it & restarted the server and some of the basic resources.
In future, if anyone notices one of our services offline, please PM me on the forums, and I'll get on it as soon as possible.
All sorted for now though.
Please... don't go crazy using all the admin functions, they are what the server crashes from - remember DM is still just a dev preview.
