Works for me on GNU/Linux.
Is 24.3.92 hanging at the exact same time that 24.3 works?
Ie, are you sure it is not an issue with the remote host?
Yes, it always hangs on recent builds while the previous builds always works. I can swap between the versions to reproduce the problem, so I don't think it's a host issue. Also, it appears to not only apply to melpa, but to all three repositories. It appears to mostly work for the first two (elpa and orgmode). I.e. it always hangs on the recent builds, but usually at the third repo - melpa.
