To clear things up, here's how it worked:
1. The company SoGo Search purchased
http://com.net .
2. Google's DNS servers went down.
3. Browsers that guess domains (especially Safari, hence the pic) couln't get google.com, so they guessed google.com.net.
4. google.com.net, a subdomain, doesn't exist, so it redirects to com.net, and the SoGo Search page pops up.
EDIT: As of now
http://com.net isn't working. But it was yesterday.
