Read timeout

We have been scraping a site by using the C10 plan and have been getting the error below constantly:

Error:

requests.exceptions.ReadTimeout: HTTPSConnectionPool(host='www.amazon.com', port=443): Read timed out. (read timeout=20)

Sample Code:

proxy_host = "proxy.crawlera.com"

proxy_port = "8010"

proxy_auth = "{key}:" # Make sure to include ':' at the end

proxies = {"https": "https://{}@{}:{}/".format(proxy_auth, proxy_host, proxy_port),

           "http": "http://{}@{}:{}/".format(proxy_auth, proxy_host, proxy_port)}

url = "https://www.example.com"

page = requests.get(url, proxies=proxies, verify=False,timeout=20 )

This error sometimes goes away by retrying. However, today after we processed about couple of thousands requests. It started to have this error for all the requests after that.

Is there any way to fix that?
