MediaWiki's handling of Interwiki links seems to not respect the protocol specified in the interwiki.iw_url field, and therefore improperly renders interwiki links using the protocol of the server the rendering is being run on, instead of what is specified in the interwiki.iw_url field in the database. An example: mysql> select * from interwiki where iw_prefix like 'wikipedia'\G *************************** 1. row *************************** iw_prefix: wikipedia iw_url: http://en.wikipedia.org/wiki/$1 iw_local: 0 iw_trans: 0 1 row in set (0.00 sec) and with that in place, and running from a fictitious URL https://wiki.foo.com/wiki/Bar, the wiki markup [[[Wikipedia:Wiki]] will improperly render a link to https://en.wikipedia.org/wiki/Wiki instead of to http://en.wikipedia.org/wiki/Wiki as it should (note HTTPS vs. HTTP).
After further review, we found that our problem was caused by a buggy extension that hooked into $wgHooks['GetFullURL']. I apologize for the bad bug report.
