ELF ATOCHEM UK Ltd. (ELF) is a division of ELF ATOCHEM S.A, which itself is a subsidiary of Groupe ELF Aquitaine S.A, a state-owned French multi-national conglomerate. ELF has thirteen sites distributed around the UK.
The work for ELF has been carried out by YACC, part of the YACC/Daemon Consortium.
YACC is now responsible for all aspects of systems and network management of ELF's corporate network, Unix and Novell systems and OSN. Most of this work is carried out over a direct link between the corporate network and YACC's Leeds offices, and is supplemented by regular site visits. Twenty-four-hour, seven-day-a-week cover is provided to other UK sites.
