I lost connection.

Absent HTTP_CF_CONNECTING_IP in os.environ, these reduce to

city = ( gi.time_zone_by_addr('REMOTE_ADDR') or
         "ÎγνÏÏÏη Î Ïλη" )

host = ( socket.gethostbyaddr('REMOTE_ADDR')[0] or
         "ÎγνÏÏÏη Î ÏοέλεÏÂÏη" )

so maybe 'REMOTE_ADDR' is not meant to be the actual argument in those
calls. Earlier versions tried to get 'REMOTE_ADDR' from os.environ, I
think.

Try Nobody's piecemeal approach, maybe.
