Rackspace doesn't actively maintain the servers by applying updates, etc. You can go to them if 3rd party software breaks on your servers and they will help you out, but I know for a fact that they don't actively update the servers, and that's a good thing considering you'd want to probably roll that into doing a release where you take that server out of rotation.

Yea but what if it was vendor agnostic? Rackspace has always been super expensive compared to the rest.
