Thing is, though, it's (CPS) perception of least utilised is based on
the load evaluators and the machine being contactable.
It (a server) having some (perhaps slightly unusual) problem or issue
with being partially available, is a tad tricky to detect. Given how
this sort of thing is currently evaluated, how would you propose that
such issues could be detected in software?
