Service Unavailable? Site.Config permission denied?

Well my site(s) have been bouncing up and down more then girls at a porn convention this past week and a half.  I have been battling my host for some kind of control to the madness.  I think I might have finally got it under control.  There fix they did tonight is in line with what I would have done if it were my server or at least had control of it.  Basically they moved my sites onto their own Application Pool and I think that will help. 

But we'll see, I am probably jinxing it.  Hopefully I can keep a reliable blog up and running from this point forward.
