Abstract: A device may correspond to a physical access controller in a distributed physical access control system. A method, performed by the device in a distributed system, may include detecting that another device in the distributed system has become unavailable; determining that a loss of consensus has occurred in the distributed system based on detecting that the other device has become unavailable; generating a list of available devices in the distributed system; and sending an alarm message to an administrative device, wherein the alarm message indicates the loss of consensus and wherein the alarm message includes the list of available devices.
