Now I'm even more surprised that you haven't gotten my point.  Or are
you just trying to play devil's advocate?  My point is that the twits
that think every admin whose network got one instance of Slammer or who
wasn't already blocking 1434/UDP should be fired for incompetence simply
don't have any comprehension of how a large network works.  It's easy to
say "pull the plug" when you're not responsible for the boxes.  It's a
bit harder when you have competing constituencies demanding opposing
actions.

At UTD we *do* pull the plug.  But I would never be so arrogant as to
demand that someone else do, because I don't know their network.  There
can be a *ton* of reasons why something wasn't done (like patching or
blocking ports) *other than* incompetence.

To answer your questions specifically, yes we do test patches, no you
can't test every situation - sometimes shit just happens, of course we
called the vendor, of course we have backups, yes our admins are *very*
experienced (our senior Windows admin is a Certified Banyan Engineer,
among other things, if that tells you anything.)

My point is not that UTD is trying to make excuses (because we're not),
but that calling admins incompetent without even knowing their networks
is arrogant and insulting, and I really wish people would stop doing
that.

I really don't care what anyone calls me.  I don't need validation from
external sources.
