Dear Colleagues,

There will be a major power outage for the JLab computing center 
affecting all compute clusters (farm and QCD) and tape Library on 
Wednesday, December 17th. The outage window will begin at 6:00 AM. Due 
to the nature of the work, only a general timeframe is provided, and the 
interruption is expected to last most of the day. Full recovery time is 
still to be determined.

Systems unaffected by the outage:

  * Interactives (ifarm &. qcdi)
  * Lustre filesystems
  * Work disk filesystems
  * code.jlab.org and associated runners

Please plan accoringly.

Best regards,
Alex
