    • Needs to be tested

● CPU

• • RAL

    • Remains low; some from job scheduling when there’s a large number of transfering FTS files in the queue.
    • Also due to contention from other VOs

  • Northgrid

    • Largely ok

  • London

    • Some brief issues with QMUL

  • SouthGrid

    • BHAM a few days outage (?), but back now.
    • Sussex; running well, but could be running more slots at the site

  • Scotgrid

    • Durham - cooling; power issue over Christmas. SRR not readable; leading to overfilling of the storage.
      • Once SRR accessible, jobs started running and data reduced to below the total.
    • Gla; disk controller appears to have died; Expected to be onlined shortly.
