A configuration node is a single node canister that manages configuration activity of the system.
If the configuration node fails, the system chooses a new configuration node. This action is called configuration node failover. The new configuration node takes over the management IP addresses. Thus you can access the system through the same IP addresses although the original configuration node has failed. During the failover, there is a short period when you cannot use the command-line tools or management GUI.
