The Service Challenges serve to test the infrastructure needed for full LHC data taking and analysis. It concentrates primarily on the robust file transfers from the Tier-0 centre CERN to all Tier-1 centres which is needed to suppport the distribution of the raw data from the experiments. In subsequent steps also the transport of the reduced datasets from Tier-0 to Tier-1, between Tier-1's and between the Tier-1's and the Tier-2's will be tested. Apart from the bare data transport  the challenges will take all  necessairy software components into account as they become gradually available. Operational aspects will also need to be understood as we upgrade in steps from test systems to a production service. During LHC data taking a 24/7 service has to be provided and the implications in terms of resources (manpower) have to be understood. As the tests gradually become more like a service the LHC experiments will use the production infrastructure for tests of their software and for their data challenges.

The intention is to have an SC meeting at each of the participating centres during 2005.
