Please see my (closed) issue, I was told to resubmit here. https://github.com/python/pythondotorg/issues/1140

Basically, I usually download a local copy of the epub and HTML docs so I can reference offline (and faster using the "custom search engine" feature of several modern browsers). Tried to download 3.6.2 and noticed I was getting a 404: https://docs.python.org/3/archives/python-3.6.2-docs-html.zip

Testing the other links on the page, looks like most are down:

```shell_session
$ curl -s https://docs.python.org/3/download.html | grep -o '"archives/.*"' | xargs -I{} bash -c 'echo; url="https://docs.python.org/3/{}"; echo "${url}"; c
url -s -I "${url}" | head -n 1'

I looked to see if this was an existing issue, sorry if it's a duplicate.
