Obviously, we need to find some faster light. On Wed, 3 Apr 1996, Wolfgang Henke wrote:

Using a real in use backbone of one of the mayor service providers, I find that a DS3 between silicon valley to Chicago has a 44 msec latency going through 4 hops. That's about the speed of light in fiber for the 5000 mile roundtrip ICMP ping packets.
Using ATM will reduce the router latency. I estimate that with TCP/IP over ATM over SONET OC-3c the latency will be reduced from 44 msec to 40 msec, only a rather small improvement. The bandwidth used on the fiber wont matter much. With OC-12c I would still expect 40 msec or so since the speed of light in fiber is the limiting factor.
