If I've understood your situation correctly - then yes, this would be an issue that is covered by our SLA. Our customer data is actually hosted on two separate storage backends for issues like failing disk drives.

Our approach on this is that when we offer a service to you, you should not be worried about how the physical equipment functions - it should just work. Hence all issues on that front would be our responsibility. Glad to talk more on this if you're interested. My contact details can be found on our company website.
