    Monitoring

    Provisionally, the cooling fault appears to have been rectified. We will allow the facility to reach its normal temperature again and will monitor stability before restarting the small number of servers that we shut down.

    Following some building maintenance this morning, cooling for our data centre GN09 is currently inoperative. An engineer has been urgently requested to attend.

    It is likely that unless the problem can be solved quickly, we will have to shut down servers in GN09.
