The guardian has been having an occasional problem where it cannot acces channels (the channels exist and are spelled correctly). One solution has been to reload the gaurdian a few times, just now I had to reload the DRMI guardian about 10 times.  Eventualy Stefan paused and reloaded it and the problem went away.  

Screen shot attached. 

We've also had some more epics freeze incidents today.  4:42:39 UTC Local 17:25:50
