We turned off weekly restarts at umich.edu at least before I got
here three years ago. The only times we do cell-wide restarts are
before the start of major semesters (just so we know every
machine would restart if any of them had an issue) and when it's
easier to do a at-once restart to do upgrades than it would be to
do rolling upgrades.
