\label{Navmap_Host_Down}

When you see a \emph{Host Down} error on your nav map, that means the
server that hosts that resource by default is currently not responding.
That means we can't find out anything about the problem from that server
right now.

LON-CAPA will try to display the correct status for the resource, but
if the problem had multiple parts, it will not succeed. However, your
information about the problem is not lost; if you completed it before, 
the system still knows it is completed. If you tried it before, the
system still know it is tried, and so on.

If this problem persists, please contact your instructor.
