What that's saying is that it couldn't look up the domain name to get the corresponding address. Most likely, that means you either don't have DNS available, or the DNS server said that it couldn't find that server. (Whether that's true or not. It's always possible for the DNS server to be wrong.) So, if you can fairly safely assume that you have a fully-functioning internet connection (for instance, if other URLs can be fetched successfully), the most reasonable interpretation of this is that the URL is, in some way, broken. I suspect that errno 11001 is a Winsock error, in which case it would mean "Host not found". On my Linux system, I get a chained exception that says "Name or service not found". Most likely, you can find this information further up in the traceback. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
