I fail to see how this has anything to do with Rackspace.

They are there to provide infrastructure, not to support you on an application level.

Rackspace's responsibility is to keep the infrastructure running and help with backups if you are compromised. They aren't there to fix your wordpress plugin's spaghetti php.

FWIW I used to run a dedicated box with Rackspace and now run about half a dozen cloud servers with them. I think they are pretty great, personally.

If the OP wants ssh, logs and all that - fire up a Cloud Server and you have an instant linux box of your flavour preference. Stop using Cloud Sites if you want more control. You're using the wrong product.
