There seems to be a widespread belief that gets propogated on various mailing lists that TCP over anycast is very very scary, and needs to be avoided at all costs. We'd like to share our operational experience showing that TCP over anycast isn't inherently unstable, and can be an exellent tool for increasing performance and/or availability in WAN services. Hopefully the presentation will be slightly interactive (how many people know what anycast is? how many people are deathly afraid of tcp anycast? ..etc) and we hope it will inspire discussion, if not tinkering.
