Thanks for the reply, but I still think there's a huge disconnect. First of all, you're admitting that it's okay for anonymous people to inflict a significant, measurable delay in page load time for my entire website. That is completely unacceptable. Also, while I'm sure your system is well designed, it probably isn't perfect (because nothing is). If your monitoring service malfunctions then the tests might never cut off. There should only be two levels of trust: people who own the server (and can test it), and people who don't own the server (and can do nothing to it).
