Do you want your own rented hardware and not just virtual machines? I'd recommend looking into data-centres then. I'm not sure what you mean by "managed" though. "Managed" (to me) normally means that they take care of the SysAdmin stuff for you. As far as up-time and making sure the hardware works, that should be included in your rental price.
