Just to add to this discussion: we are having problems with node power
supplies (the ones with the red dots on the status page actually have
dead power supplies). Unfortunately, the first symptoms of failing PSs
are CM lockups and nodes stuck in on or off state; it looks like we will
have to replace all of them which is not a trivial thing to do. We are
trying to find ways of using interim software solution that will
(hopefully) prolong the life of power supplies as well as enable us to
do incremental replacement (rather than force us to shut down the grid
and replace all power supplies at once).

PS: Even better page for big grid status is
http://www.orbit-lab.org/wiki/Status/Grid - it has a webcam feed as well
:-). (status pages do not auto-refresh so you will have to do it
manually - after all they are not really finished yet as you will
discover if you try to select individual nodes).
