Hello,

I'm trying to do a home grown load balancing solution that needs to
determine which of the two data centers a visitor should be sent to.
I'd like to do some type of a network proximity calculation that
includes latency and number of hops which will allow me to redirect the
user to their "closest/fastest" server.

I know all about CDNs and Appliance Load Balancers (F5); I'm looking for
a custom software solution instead.

Any pointers is much appreciated.

GP.
