At 5:00 PM, Friday, January 23, 2009, the general access Linux servers helsinki.cc.gatech.edu, mikkeli.cc.gatech.edu, and tampere.cc.gatech.edu will be rebooted to clear up networking problems created by stale NFS handles. This will affect the interactive ssh users of these servers. During this maintenance period, which is expected to be completed by 5:15 PM, January 23, the systems will be temporarily unavailable while they reboot.
