Abstract	During operation at instantaneous luminosities of up to 2.1 10^{34} cm^{-2} s^{-1} the front end chips of the ATLAS innermost pixel layer (IBL) experienced single event upsets affecting its global registers as well as the settings for the individual pixels, causing, among other things loss of occupancy, noisy pixels, and silent pixels. A quantitative analysis of the single event upsets as well as the operational issues and mitigation techniques will be presented.
