There is a mailing list and a wiki page. More info here:

I lead (well I try to) a team of hardware designers specializing in
(among other things) synchronization of distributed systems. We designed
a system inspired by the way national metrology labs manufacture UTC,
using high-precision GPS receivers and atomic clocks. This system
allowed the measurement of neutrino speed to unprecedented levels of
accuracy. The neutrino beam is shot from CERN through 732 km of Earth
crust in a straight line all the way to Gran Sasso National Lab in
Italy. The geodesy people measured the distance very precisely. We
measured the time very precisely. The physicists made a very good
analysis leading to a good evaluation of neutrino speed, but it turned
out to be bigger than a very sacred number of Physics. So we are all
very stressed :)

Sorry for the OT. Back to OSHW now!
Cheers,
