The Bots ARE back up as of 8:00am USA MST this morning.
There was no announcement of any kind that I could see.
You will MOST likely have to do a fresh install to get your bot working.
Download from the main demonbuddy download page (before entering forums).
Make sure your current DB is uninstalled or in a seperate folder. I like to move my plugins and such out, delete the rest, put the new DB in, then drag and drop the plugins and such back in for a quick painless install.
