bad idea?

[Jeremiah Kristal <jkristal () on2 com>]

Given a small, globally routable netblock to be used for front-end web
servers, and a strong aversion for using DNS for any type of load
balancing, would it be reasonable to build two identical servers farms
with the same public IP addresses and rely on the BGP sessions with the
hosing providers to remove one advertisement in the event of a problem? 
I've been looking at ways to ensure that the webservers are always
available, short of building a network connecting hosting facilities.
