Large end-user companies generally multihomed by that time, and you
generally did that by BGP4 at the time (post-1994), and before that
BGP3, and before that EGP, and before that... well, there was little
"commercial ISPness" other than NSFNet connectivity and the regional
networks back then so multihoming was somewhat of a moot point.

Thank you again, UUNet/Alternet and PSI!
