A render farm can be in one of several states, and this is shown on the render farms list. Each status is shown as a color-coded label with the name of the status.

The following table shows the possible statuses, and explains what they mean.

Green (solid)EnabledThe render farm is active and can be used. If you want to make it unavailable, you can disable it.
Orange (stripe)PendingThe render farm infrastructure is being set up by SimpleCloud. 
Gray (solid)DisabledThe render farm exists in SimpleCloud, but it has been disabled so that it cannot be used. If you want to use it, you will need to enable it first.
