I'm running scrapy to crawl through sites.  I wanted to crawl
http://clinicaltrials.gov/, once, but that was not working... with I thought
was weird.  As a result I started pinging various sources just to make
sure that I can ping them in the first place.

This isn't a huge deal since my project will be using bing, but through
that it was weird that I couldn't ping www.google.com and www.cnn.com.
