Sure, start another connection to the server with another easy handle and
if that fails, your connection is down :)

Seriously, there's other way to tell when the "Internet connection" is down.
There are often platform-specific ways to tell if the local Ethernet cable
is unplugged, but what if the machine is getting its Internet via PPP?
Or 802.11? Or ARCnet? Or RFC1149? Or all five for redundancy?

Also read today's thread called "Cable Unplugged!".
