Yes, but many larger ISPs will cache the DNS record anyways even if they 
are not supposed to.

You might want to look into some other way to get what you want.  Do you 
have enough bandwidth to set up a box using NGINX or Pound (load 
balancing web proxies that can detect when a machine is not responding) 
somewhere, then have it transparently switch between the two?
