这个问题很正常，频繁的访问某个网站会被认为是DOS攻击，通常做了Rate-limit的网站都会停止响应一段时间，你可以Catch这个Exception，sleep一段时间然后重试，也可以根据重试的次数做exponential backup off。

IOError: [Errno socket error] [Errno 10060] A connection attempt
failed because the connected party did not properly respond after a
period of time, or established connection failed because connected
host has failed to respond
