The German Antarctic research station “Neumayer” is built into the Ekström ice shelf in Atka bay (East Antarctica). Several observatories for meteorological, geophysical and air chemical research are operated year round in the close vicinity of the station. The station’s computer network is complex, and yet must be though set up to be fail-proof, redundant and easy to maintain. IT-services on “Neumayer”, administration of the network and IT consulting for the computer facilities and observatories was provided by FIELAX.
