The negative to this type of arrangement is that the colocation customer bears all responsibility for maintaining the server itself. Colocation hosting providers have been encouraging customers to lease dedicated servers serviced and maintained by the colocation company itself. One big benefit to this approach is that, by renting server space through colocation hosting, customers do not have to build and maintain the infrastructure necessary to host their own servers and maintain Internet connectivity or hire specialized personnel. That is what the colocation hosting provider is for. A shift of infrastructure responsibility to a colocation service results in huge financial savings to a small or medium sized company on the way up.
