I'm sorry to hear you are having issues. All of the hardware used in your server was brand new, high quality hardware. Failures like this, especially multiple failures are very rare. We are looking into the cause and will keep you updated on the ticket you have open.

Service and support are always going to be more important than hardware. Liquidweb uses good hardware so failure is rare but, many parts can be DOA from the factory (I have horror stories to tell about printers and hard drives at Office Depot..).
