  In May 2011, the IceCube neutrino observatory with one cubic kilometer
instrumented volume started full operation with 5160 sensors on 86 strings and
324 sensors on 162 IceTop detectors. The fine-tuning of operation and
calibration of the detector is still in progress while a very high uptime of
well above $98\%$ is obtained. New analysis techniques rely on veto techniques
for enhanced rejection of atmospheric muon and neutrino backgrounds. We will
give an overview of recent results including the techniques of searching for
starting tracks and some comments on the reported evidence of astrophysical
neutrinos at energies above 30 TeV.
