Is it really? yuck. When I saw this post, I thought this would be reasonably simple... After all, all you need is something to ping/hit the webserver and report when it can't. To be honest, you can't account for every possible situation. Sometimes murphy's law applies. But if you can find a service that at least lets you know when it's hitting your server historically in some way, you should purchase it and get on to worrying about other things. If the company doesn't perform, you can deal with that issue at that time.
