A collegue of mine DoSsed natalian.org with Jmeter.
It was only pulling the index.php and it seemed to hold up with a 100 concurrent connections. Then after awhile Wordpress seemed to lose contact with the mysql database and my site didn’t respond for more than 200 seconds. 
It came back pretty quickly after he stopped the test. I was told there was only one error, though I can’t see anything odd in the logs.
I am probably going to move over to Dreamhost in the near future as the machine is quite badly specced and on a home connection.
