Country network's down (4)
I believe the answer is:
land
'country' is the definition.
(I've seen this before)
'network's down' is the wordplay.
'network' becomes 'lan' (LAN is an example).
'down' becomes 'd'.
'lan'+'d'='LAND'
(Other definitions for land that I've seen before include "win" , "Lift with ropes and pulleys" , "Woman with tenants, or a pub" , "Property" , "Country, state" .)
