Unfortunately you're not going to be able to guarantee a proxy's functionality unless you actually use it to access something.

If you're doing your connections on a periodic basis, I think you just need to keep a list of possibilities and send yourself alerts to refresh the list if it hits some low threshold as you drop non-responding proxies from the pool.

Update: Wording updates. Remove syllogism.
