Usually you do such things using some dynamic routing protocols (OSPF,=20
BGP, RIP).

But it need cooperation from upstream provider. Quite good solution is=20
using some kind of monitoring tool (nagios for example), which=20
reachibility of some hosts and using that information you can alter=20
routing table.

Or you can use shell script, combined with ping and cron :)
