If your site/service links to or uses pypi.python.org, you should start using pypi.org instead: https://warehouse.readthedocs.io/api-reference/integration-guide/#migrating-to-the-new-pypi

Current Code:

updatable/updatable/__init__.py

Lines 75 to 80 in e812bbf

	pypi_url = 'https://pypi.python.org/pypi'
	if version:
	package_url = '%s/%s/%s/json' % (pypi_url, package_name, version, )
	else:
	package_url = '%s/%s/json' % (pypi_url, package_name, )

New URL is https://pypi.org/pypi/%s/%s/json, so the code should look like:

 pypi_url = 'https://pypi.org/pypi' 

 if version: 
     package_url = '%s/%s/%s/json' % (pypi_url, package_name, version, ) 
 else: 
     package_url = '%s/%s/json' % (pypi_url, package_name, )
