One aspect of the invention comprises a method of operating a network for providing services to subscribers, the network including a configuration system comprising: a core system comprising primary and secondary cores, each core being separately capable of controlling operation of the system; at least one cell connected to the core system; and at least one network element connected to the cell, each network element supporting a number of subscribers for provision of the services; the method comprising: operating the configuration system using the primary core; monitoring operation of the primary core for a failure event preventing the primary core from properly controlling operation of the configuration system; on detection of a failure event, transferring control of operation of the configuration system to the secondary core; following correction of the failure event such that the primary core again becomes capable of properly controlling operation of the configuration system, configuring the secondary core such that it is no longer modified and synchronizing the configuration of the primary core with the configuration of the secondary core; and transferring operation of the system back to the primary core.
