Yes, Tony. It was absolutely fair. It was certainly not your (or
Cisco's) fault. It was a huge effort on the part of a small number of
Cisco engineers (I assume that you and Paul wrote most of the code) to
get a complex protocol stable and ready for implementation in far too
little time. It was utter insanity and it all worked! (Just in time for
the death of the PRDB).

In no way was I criticizing your efforts. I just remember that message
and thinking how much testing and planning we do today before rolling
new code onto production systems. The idea of reloading production
routers with code we absolutely knew would prove buggy on a weekly (or
more than weekly) basis seems so unimaginable today.

I'm looking forward to seeing Milo at NANOG 52 next month in Denver! I'm
sure that he remembers all of this.
