Yeah, my Cubes really took a hit, there running 94-97% on my end. Down 90%

I'll move them till the problem is fixed.
All problems are fixed now, every BTC Guild server (including validation server) has been reverted to the same software it was using for the last year.
And my machine is back to running at the proper rate. When the old stuff works and the new stuff doesn't... You have your work cut out for you.
