I suspect it's getting hammered at the moment -- the Iran check returned an error for me, and the Google page rank check for "google.com" or "yahoo.com" still reports "Sorry, we couldn't seem to find that domain in Google's cache." To the developer: this is a great time to refine the error handling (plus scaling, of course). :) E.g., make sure when the requests fail (for whatever reason) that it can report this back to the user clearly.
