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.
