When loading a bucket listing that is previously known to work, the page appears blank.

This is because the JS refuses to load:

This seems to be because Safari is trying to load the content over plaintext:

Even though it is definitely an HTTPS link in the source tag:

Note that Chrome seems to complain about a similar issue:

This seems to be because GitHub is issuing a 301 redirect to a non-SSL URI:

I am working around by hosting list.js myself. That seems to work fine.

Known config: OSX 10.11 (15A284), Safari 9.0 (11601.1.56), Chrome 45.0.2454.101 (64-bit)

I assume this is actually GitHub's bug, but I don't think they have an actual bugtracker :-/

Thanks for the report and detailed analysis - really appreciated.

Can you share the site where this happens? I've got two sites that seem to be working ok e.g. https://assets.okfn.org/ and http://data.openspending.org/ (in chrome and safari).
