A power device includes an input configured to receive input power from a power source, power circuitry, a power output, a network module, and a controller. The controller is configured to operate the power circuitry to provide output power to the power output derived from the input power and to communicate with at least one primary server via the network module. In response to a determination that communication with the primary server has failed, the controller is configured to attempt communication with a domain name server. In response to a determination that communication with the domain name server has failed, the controller is configured to identify that the network has failed.
