Things break, but you hope they don't all break at the same time.  If
the KVM goes down, it's probably not at the same time you need to fsck
a server that you just rebooted.  And when other things break, the
goal is to have enough redundancy on hand to be able to fix the
problem until you can replace whatever broke without dropping
everything at 2am.

Also, depending on your provider, a remote KVM winds up being cheaper
than the cost of a few remote-hands calls.
