The system Ask is describing is the traditional method of using anycast to
geographically load-balance long-lived flows. The first time I did that was
with FTP servers in Berkeley and Santa Cruz, in 1989.
I did a bigger system, also load balancing FTP servers for Oracle, their

Although they used the word "anycast", they're just load balancing.
