There is a hierarchical structure in place to provide operations support. This consists of the following elements: Regional Operations Centres (ROC) See the following operations portals for more information: EGI Operations portal: http://operations-portal.egi.eu/ OSG Operations portal: https://twiki.grid.iu.edu/bin/view/Operations Core Infrastructure Centres (CIC) These centres provide a grid "operator" on shift - with the responsibility rotating through the CIC centres one week at a time. The "CIC-on-duty" provides the oversight for the grid operations, using a variety of monitoring tools as well as direct problem reports to find and analyse operational problems. Problems are reported to the grid sites and their supervising ROC for follow up, the CIC will ensure that problems are followed up and will provide the escalation process if needed. Teams of experts at CERN and throughout the project also contribute to the analysis and resolution of problems according to expertise. Current centres are as follows: CERN (Geneva, Switzerland) CCIN2P3 (Lyon, France) CNAF (Bologna, Italy) RAL (Didcot, UK) Russia ASCC Taipei In the US the OSG Grid Operations Center provides 24/7 support for US sites and use. There is an automated problem transfer between the EGEE and OSG operations. The CICs follow problems in the full grid infrastructure, including those sites not part of the EGEE project. In that case the oversight and local support for problem follow up falls to the regional Tier 1 centres or falls back to CERN. Access to the operations procedures, checklists and further details can be seen via the CIC portal maintained at Lyon.
