Usage notes
* (Internet) This is different from having crashed, in that, if the system has crashed, it has become totally non-functioning and will not respond to any probes; it will seem to be offline, disconnected, or powered down. If a server is wedged, it will respond to minor probes or requests, but will not be able to completely service the request to completion.
