Python - No conecta ping timeout

Wenas anda haciendo un cliente para terra por IRC y no me devuelve informacion nada mas q:

<irc cmd="ERROR" rest="Closing Link: [83.33.146.4] (Ping timeout)" />

el codigo es:

#! /usr/bin/env python

from sys import argv, exit
from socket import *
from time import sleep
a = str(argv[1])
conecta = "-c"
terra = "213.4.130.190"
paso1 = "<raw>PASS NULL</raw>"
paso2 = "<raw>NICK probphyton</raw>"
paso3 = "<raw>USER P01 - - :chatFlashXML</raw>"
if a == conecta :
sock = socket(AF_INET, SOCK_STREAM)
sock.connect((terra, int(6969)))
sleep(1)
sock.send(paso1)
sock.send(paso2)
sock.send(paso3)
datos = str((sock.recv(1024)))
print datos
sleep(5)
sock.send("<raw>JOIN #toledo</raw>")

Por que podria ser?
