We just pushed out a resolution to Issue 381, updating the path to the license engine. The license engine (the cc.engine application) is responsible for handling the license selection portions of the website as well as the deeds. Some background may be helpful.

When we launched CC0 earlier this year we made a conscious decision to locate the deed on a different path than the rest of the license deeds. CC0 is a waiver , not a license , so the deed appropriately is located at http://creativecommons.org/publicdomain/zero/1.0/ (as opposed to the license deeds which URLs that look like http://creativecommons.org/licenses/by/3.0/). At the time we decided to leave the CC0 chooser in the same group as the other choosers. This unfortunately gave us a URL that contained license in it -- http://creativecommons.org/license/zero/ -- which caused confusion for some users. Is it a license or isn't it?

It's not.

So starting this afternoon we've relocated the license engine to http://creativecommons.org/choose and CC0 to http://creativecommons.org/choose/zero. Redirects are in place so you shouldn't notice any changes.
