A process for preparing aerated ice confection particles by manufacturing an aerated ice confection in a mass; further freezing the mass cryogenically to a temperature close to the glass transition temperature of the aerated ice confection to form a aerated frozen mass, and comminuting the frozen mass to aerated ice confection particles with a high surface area to volume ratio. Pluralities of virtual machines are arranged on one or more computing devices and define, for example, applications specified by a user and shared services approved by the enterprise. A cable tracing arrangement includes a tracing signal generator at a channel interface of each remote node, which generates a tracing signal when cable tracing is desired. Each ball has a bottom end projecting over a bottom of the base.
