To go a little deeper into what I witnessed up close.

Had we had the option of having the server log a problem or even launch an
email, we could have handled the configuration.

After the post-mortem I was talking to a colleague who said he too had
requested a safety breaking system from some tool makers and was "laughed
off."  Take what I am saying here as umpteenth-hand retelling of a fib
because we never bothered to make the same request, we just rolled our own
script (because we had the staff available to do this, although they
weren't ordinarily dedicated to this function).

It's not a question if this can be done.  It's a question of how can this
be packaged for operations.

To sum up something - one thing I learned during my stints in operations -
many of the assumptions held by protocol engineers and architects about
how a protocol is put to work are far from reality.  (Not that the
engineers and architects are wrong in their approach but the assumptions
are wrong.)  I don't mean that operators are using bailing wire and duct
tape to reap huge profits, but the approach to sound operational practices
sometimes runs counter to what I learned to be sound in the lab.
