Group Mandate
Computing Facilities

Manages and operates the CERN Data Centre and associated Computing Facilities.

Communication Systems

Responsible for networking and telecommunications services for the Laboratory, including the campus network for office and Wi-Fi connectivity, a technical network to support accelerator operations and critical laboratory infrastructure, a high-performance data centre network to support physics computing, including high-bandwidth connections to computing facilities around the world, fixed and mobile telephony services, and TETRA digital radio services for the Fire and Rescue Services.


The Database Services Group (IT-DB) is responsible for current and future databases and their platform for accelerators, experiments and administrative services. It is also in charge of hosting Java Web applications as well as critical engineering and administration applications at CERN scale. Moreover, the group provides scale-out analytics services including Hadoop, Spark and Kafka for CERN and the LHC experiments.

Departmental Infrastructure
