When they start later this year, the LHC experiments will generate an unprecedented amount of data, accumulating over 15 Petabytes every year. The Worldwide LHC Computing Grid project was started in 2002 with the goal of deploying a distributed computing infrastructure to manage the LHC data. It combines the power of more than 140 computing centres in 33 countries. Eleven of these centres, the so called Tier-1s, are directly connected to CERN with dedicated network links and will be receiving a copy of the RAW data online. These centres will perform massive processing of the data and redistribute the output to other sites worldwide for further analysis. The Spanish Tier-1 for the LHC is located at PIC, near Barcelona. This talk will present the status of this service and its readiness for data taking.
