I'd be a little wary of that "< 400" result though. You may (or may not) 
want to follow redirects, and if you get a 418 you may want a cuppa <g>.

and due to the extra hops involved, I probably wouldn't try for 
"https://www.google.com". DNS resolution will add tens to over a hundred 
milliseconds to a web command, so if you're going to go that route 
instead of opening a socket I'd go straight to "http://8.8.8.8:53".

curl -v --trace-time 8.8.8.8:53
20 milliseconds

curl -v --trace-time www.google.com
50 milliseconds

But otherwise, yes... there is no way of checking for the internet 
without connecting to the internet.
