So what's the problem in *testing* your software before putting in general
release?  Running the "upgraded" software on a testbed machine before
putting it on-line?  Dropping contact information is kinda's
not like this is some obscure, only-happens-on-wierd-configurations,
blue-moon bug; this is pretty obvious.

Hell, even *I* test a new part in a computer before closing the case and
pronouncing it fit for'd think NSI could do the same.  It's basic
common sense, after all.

Or maybe testing their code?  Or would that have been more expensive than
writing a patch?

the way it should before you step on your privates in front of a few
million people.  That's certainly what I would have done!  It's pretty
obvious and yes, even machine (or two, if you want to verify
network performance).

And never learned to test before deployment?  I learned that in high school
BASIC classes....
