Abstract: A method of re-routing a connection request by an end user of a network, comprising: selecting one or more proscribed destination sites in respect of which requests are to be re-routed; communicating information relating to the identity of the at least one proscribed destination site to a network service provider to which end users make requests for connection to various sites; arranging with the network service provider so that upon receipt by the network service provider, of a request by an end user for connection to a proscribed destination site, a connection is established between the network service provider and a desired destination site; and wherein the end user's request for connection to the proscribed destination site is routed to the desired destination site.
