If you can't accept a short outage from the free website from a charity then the RPi may not be the hardware for you. Go to Lenovo or Dell and pay big $$$$$s for their expensive hardware with an expensive 24*365 support contract.
The Raspberry Pi Foundation appear to have a good, strong, reliable service from their hosting provider backed with an effective service level agreement.
