The ASPN page you requested — /recipes/langs/python/ — no longer exists.
In July 2010, ActiveState's ASPN site was retired. The most popular elements of that site were moved here on ActiveState Code, in particular ActiveState Code Recipes (previously the "ASPN Cookbooks"), and the List Archives (previously "ASPN Mailing Lists and Archives"). Apologies for any inconvenience.
If you believe this is a bug, please report it. Thanks!
