- FUP is a policy that governs unfair usage of the network by utilizing excessive network resources causing inconvenience to other customers on the network. In such a situation, systems restrict the user to certain speed of bandwidth to minimize such abuse and alert the administrator. Fair Usage limits are defined basing on the average of maximum utilization by highest bandwidth users on the network. Once the user has reached the fair usage download limit, the account will be restricted to a bandwidth that is lesser than the subscribed bandwidth. However, the same will be reset to the subscribed bandwidth on every 1st of a Month or at the start of your next billing cycle.
