"REDUNDANT " usually means it is hosted in multiple locations. In-case something goes wrong. If one server/host goes down, another steps in to takes its place. Another form of "REDUNDANT" could also mean, based on ips geo-location by default viewers will be directed to the host closest to their location. (post is kind of old. hope i helped)
