Unknown Machines are machines that have not communicated with the
availability database for more than 10 minutes. These could be in use, powered
off, broken or available or this could be the result of a network issue. Please
note that in an effort to save energy, many machines are powered off each night
- thus being reported as unknown. ECN Supported machines are checked for last status change.
The last communication time is given in the details
section for each lab area.
