Broken links to Sphinx

The page below (maybe others?) has a number of broken Sphinx links:
https://docs.python-guide.org/writing/documentation/

The links point to http://sphinx.pocoo.org/, which returns error 400.
They should instead point to:
https://www.sphinx-doc.org/

Thanks David, want to create a pull-request to fix those? That'll be an easy one to contribute :)
