Ima using Python v3.3.2 Dave

The host = socket.gethostbyaddr( os.environ['REMOTE_ADDR'] )[0] or 
'UnResolved' should not have give an error since i explicityl tell it 
that if it cannot resolve dns the ip to hostname to set it as "unresolved"

The error appear ONLY when i CloudFlare superhost.gr

If i pause tthe domain form CloudFlare then my website loads properly.

What is now proved was at first only imagined!
