Systems and method for selecting points-of-presence (POPs) to be used by client systems when accessing network resources from the Internet are disclosed. An access monitoring system capable of monitoring client system usage compiles usage profiles for each of a plurality of client systems as POPs are used to access the Internet. The POPs may charge for Internet access according a flat periodic fee, hourly rates, per-port rates, or other arrangements. Periodically, the access monitoring system evaluates the usage profiles to determine whether the client systems could have obtained access to the Internet for lower access costs if different POPs had been used. If so, the access monitoring system identifies the appropriate, cost-effective POPs and generates one or more scripts instructing the client systems to use the appropriate POPs. To subsequently access the Internet, the client systems execute the scripts and establish communication with the appropriate POPs. The process of monitoring usage and reevaluating which POPs should be used continues as desired. POP selection can also be conducted to balance load between various POPs based on the usage patterns described by the usage profiles.
