  IceCube uses the entire earth as a shield. Basically only neutrinos going up through the detector is considered.

    I guess that depends on how you define 'up' (are you looking at the entire planet or standing on the pole) As I understand it these days they grab all samples and are now able to distinguish 'downward' coming neutrinos from cosmic rays in software
