most likely the physical hardware was never stolen at all, the farm was pointed somewhere else, the question is why..
Makes no sense. This would require far more than a single rogue operative inside AM. ASICMINER has actual employees and a large mining infrastructure, not a single laptop controlling 5000+ miners.
Only thing we can be sure of is that whatever is going on is going to make one hell of a story.
All it probably took was someone redirecting the proxy server. When you have a large scale farm you obviously use a proxy to move them from pool to pool. I think until Mr FriedCat makes a reply we will never know.
