Given a small, globally routable netblock to be used for front-end web

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.

being a customer stinks
If you have cisco, you could use a BGP non-exist-map and advertise-map and conditionally advertise that globally routable block in the case of an outage, or have your provider do so. The main concern here being a flapping interface, of course. Does anyone know of a way to get around the flapping/dampening issue?
