As someone else mentioned in this thread - would colocating the servers be a workable solution for them? Put the servers some place where the redundancy exists already.
My vote goes to the traditional BGP multihomed solution. It's the right way to solve the problem and the easiest to manage. If getting AT&T to do BGP and buying a BGP capable router (they don't even need full routes...so so anything that'll speak BGP, take a pair of default routes, and handle whatever their traffic level is will do) is too costly[1], another possible option I've not seen mentioned is VPN. They could put one machine/router somewhere with decent redundancy and setup a VPN gateway at their office that connects to the colo'd device. You might even offer this as a service. Spammers have been doing this for years. It makes moving their operations easier as their public facing servers get cancelled. All they do is move the VPN server(s) and their systems that do all the "work" remain online and hidden. [1] If only I had a dollar for every time a client said redundancy was too expensive to have, but when their non-redundant stuff went offline, they claimed to be losing millions of $ per small unit of time. ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route | therefore you are _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
