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

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

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