Let's also not forget that ping is completely unreliable way of validating machine health. Just because an interface responds to requests (icmp echo for example) does not mean that services on that box are properly listening. I hear this all the time:
"I pinged your machine so I know it's working, but I can't see your website. What else could be wrong?"
