Pretty sloppy on Apple's end if you ask me. Why check for a domain that you don't actually own? Imagine if someone bought the domain and worked out how to maliciously use it to their advantage? (I seriously doubt that's possible though). What kind of info was being sent to this domain, was it just a standard request to see if there is connectivity or was other information sent that could be used to identify a user? Sounds sub-par just like how the Wifi functionality does a request to: http://www.apple.com/library/test/success.html
