Default route with object tracking

Hi list.

I'd like to setup my default routes to the Interwebz to be conditional on
reachability of something on the Interwebz. I got two different ISPs (no
BGP). I'm trying to figure out what would be a reliable object to track?
Meaning, it's probably not reasonable to track my ISPs default gateway,
since it does not protect me from someone on the ISP side screwing up. I'm
thinking of tracking something like, but am not sure if after I
resolve for the first time, it will be simply tracking an
arbitrary server (or some load balancer).

I wanted to see what experienced folks think is a reliable tracking target.
Any comments are much appreciated.

thank you,
