[Clusterusers] Short cluster downtime

[Wm. Josiah Erikson]

Hello all,
    I don't think anybody will care, because it doesn't look like 
anybody's using the cluster right now anyway, but I'm going to shut down 
most of the nodes to the cluster for a bit because they're doing AC 
maintenance and room won't be air conditioned for a few hours. Email me 
in the unlikely event that this messes up your plans.
