 *Description*: In Red{nbsp}Hat build of MicroShift, use _offline_ for endpoints where no network is present or all network cards are unplugged. Also use _offline_ to describe endpoints where both conditions are true. Examples include edge devices in physically remote locations. For situations where a network is present, but devices or hosts are isolated from it, such as in restricted networks or air-gapped networks, use _disconnected_.
