Thanks! I've just purged cache. It should work now.

@ewdurbin is there a way to solve this on Fastly or Heroku's end? I created a command to purge Fastly cache, but I doubt this will be enough to solve this issue.

See #1420 and #1423 for previous reports.

@ewdurbin here's my WIP branch: master...berkerpeksag:fix-fastly-cache

@berkerpeksag if you open a PR for that WIP I can comment inline with suggested improvements.

I'm getting this as well although it was closed as fixed a few hours ago in #1448.
Can I help out with a web transaction monitor that'll test the live site and signal when it's back online?

I ran into this yesterday, and it's indeed fixed for me now. Does anyone think what the site code reports is a problem? That is, claiming javascript is disabled, when that isn't the problem - at the time I verified that javascript in other pages was otherwise working normally.

I agree, @mwichmann that false error message looks like a separate bug we should file and take care of. If I understand correctly, the problem is a 404 CSS URL.

FYI a more permanent solution is being worked on in PR #1427

This is still happening (which I assume you know given the update an hour ago). The Python 2.7 source download page links to https://www.python.org/downloads/release/python-2716/ which gets a 404 on its stylesheet https://www.python.org/static/stylesheets/style.3dbbbf7ee488 . 2715 works, as does 2713, most of the other 27\d+ urls don't.
