So the rumor is that the whole faster than light neutrino result was actually due to a loose cable. While there may have been other issues with the result, the article that I linked to above claims that it was due to "a bad connection between a fiber optic cable that connects to the GPS receiver used to correct the timing of the neutrinos' flight and an electronic card in a computer." Apparently there was a delay in the equipment that was unaccounted for that equaled roughly 60 ns.
Having dealt with high precision time measurements before I know how difficult this can be. All electronic equipment has a delay and if you don't calculate it right your experiment will be off. It could also be that they had the wrong length of fiber (hey it happens!), but to get a delay that long they would have to have about 18m of extra fiber (again, it could happen). So I am banking on it being an electronics problem that caused the delay. So if this proves to be the case .... wow. Cautionary tale.
