    As a very basic, adhoc and unreliable test,
    you could just ping the machine.

    If you want a more permanent solution, look into monitoring and alerting tools like nagios, xymon, etc.
    You must always face the curtain with a bow.

    Yep - I completely agree. It's pretty much impossible to tell whether a machine is either powered off or if its network has failed because some idiot trod on the wire and pulled it out... You need physical access to the machine to check. With some kind of monitoring software you might get advance warning of impending failures or at least some extra detail to see what has actually happened.

    If you are somewhat familar with the network that the remote server is attached to, you could also try similar test to them, this would help to eliminate the idea that a switch, or router or network segment is down. Otherwise monitoring tools like whats suggested by others would work fine.
