Hi,
Following last year's Native HTTPS efforts¹, I've pushed a change² today that redirects all the old secure.wikimedia.org URLs to the respective native HTTPS ones, e.g. https://secure.wikimedia.org/wikipedia/en/wiki/Main_Page gets redirected to https://en.wikipedia.org/wiki/Main_Page
The redirects are HTTP temporary redirects (302) for now. I'll soon switch them to permanent (301), please do let me know if you see any breakage in the meantime.
Regards, Faidon
