Even a datacenter by itself plugs in to more than one backbone (network provider) So a datacenter itself has more than one connection into it. So what I am saying, if you want to fail over between data centers, that is not something you configure in tomcat, or in your own network, that is something you probably arrange with the data centers or the network providers, cause if your data center gets shattered in an earth quake, all the routers in there will be dead anyway.
