As Max stated, you can set triggers based on thresholds that are monitered
via multiple methods in Cisco IOS. That way you could force the route down
dynamically. There's always a risk when letting the machines do the thinking
but this would help in situations like this. Can't speak for other vendors
but I'm sure the features are similar.

Quick question, are you running with a default route from your
provider?   If so, you're better off either finding another provider,
or upgrading the router (if necessary) to carry a full table.   If
they do something to partition their network, you will see the
decrease in routes learned from them, provided you see those routes
and not the default route as asked above.
