I remember back in 1993 or 1994 getting a note from Tony Li chastising
us for running BGP4 code that was over a WEEK old. How could we possibly
expect things to work with code that far out of date?

The amazing part is that BGP4 not only worked, but was very stable less
then a month later when NSFnet shut down an se had to go to BGP4 to peer
with everyone (like MCI, Sprint, NASA, and UUnet).

Yep, it booted in the lab, all right.
