A partially interconnected network has a plurality of topological nodes, each of the topological nodes having at least three direct point-to-point topological links connected to other topological nodes. Each of a proportion of the plurality of topological nodes is connected to one of a group of point-of-presence (PoP) units. The group of PoP units is arranged to provide access to a selected service or services, one or more of each of the at least three direct point-to-point topological links from each topological node not being connected to one of a group of PoP units connecting to one or more than one of the plurality of topological nodes being connected to one of the group of PoP units. There is at least one choice of routing between any two topological nodes, the choice of routing being either via two topological links connected in series at another topological node or a direct point-to-point topological link between the two topological nodes.
