mburns's Journal: Finding the Problem in the Neutrino Experiment:

For this the kudos go to Scott Gray, publishing as AZSquib - see http://blog.vixra.org/2011/09/19/can-neutrinos-be-superluminal/#comment-11088 . It is regrettable that, as quickly as the problem was identified, it was not found sooner, before public attention was expended on the reported results. As discovered by AZSquib, standard issue Ethernet quartz crystals and circuits were used to timestamp event records. These were never calibrated, and their possible variation was not included in the error analysis. Neither the official specification nor the usual accuracy are sufficient for the task of measuring the speed of neutrinos. The experimenters used a master clock, but to no real effect.
