PBR-based failover and DNS

[dprakken1]

I am trying to design a failover solution that uses Policy Based Routing between two ISP's - using one router getting bonded T1's from one and a cable modem ethernet handoff from the other. It seems fairly straight forward from the PBR aspect, but what happens to DNS when the link fails over? The basic layout is:

serverfarm->switch->firewall->pbr-router

Thanks
