Thanks for reporting this problem. I should have said that in my first post. I found more:

Edit: I disabled the 4 mirrors that are shown down. That should enable Mirrorbits to perform correctly. If not for a work around you can use this command and select an individual mirror:
sudo om-mirror-selector.sh -m
I believe that command lists them in order of some perceived download speed, not sure about that. Since I help maintain the MirrorBits I use Mirrorbits not the individual mirror approach.
