How do I check if a website is up?

[Paul Weaver]

However if you use a squid proxy, running the service on the cache would
be a better choice. 

If not, running on your external gateway might be a good idea. After
all, if your internet connection goes down, it doesn't mean
www.google.com isn't available -- it means you can't see it.
