Here is the latest proposal for a Usenet backbone. This is very similar to what we have before, and I expect very few changes before it goes into effect. Would anyone who has a problem with it or suggestions for changes please let me know?

(sdcsvax-australia link via magtape once/week) (philabs-mcvax via tin cans and string) Each backbone sites becomes responsible for their own geographic area and should help arrange the configuration of that area. Some sites also gain responsibility for some areas that are not geographic, e.g. seismo for the ARPANET and we13+burl for Western Electric. Other corporations may wish to remain linked up, instead of going geographic, e.g. decvax and decwrl will probably want to maintain a connection. Most geographic areas are obvious, however, note that zehntel covers the northern SF bay (SF, Berkeley, east bay) and hplabs covers Silicon Valley; sdcrdcf covers Los Angeles; duke covers the Research Triangle, philabs covers New York state, mcvax covers Europe. harpo, mhb5b, and spanky cover BTL WH, MH, and HO; we13+burl cover Western Electric, Long Lines, AT&T, and BOC's (but not BTL or ABI). ABI connects in through spanky. The following sites which used to be on the backbone no longer are: ucbvax (to be connected to zehntel) sri-unix (to be connected to hplabs or zehntel) cca (connected to decvax) npois (becomes part of BTL backbone) ihnss (replaced by ihnp4) ucbvax and sri-unix and brl-bmd are still important as ARPANET gateways for fa newsgroups and certain net newsgroups, so they are within one hop of the backbone. The following existing Usenet links should be cut after the above links are established. (This is a recommendation, not a requirement.) DO NOT SEVER THESE LINKS YET - THIS IS NOT FINAL! tektronix-ucbcad ucbvax-decvax sri-unix-cca ihnp4-houxi duke-decvax duke-harpo npois-harpo sdccsu3-sdcrdcf (replaced by sdcsvax-sdcrdcf) sask-utah-cs (replaced by alberta-sask) decvax-microsoft (replaced by uw-beaver-microsoft)
