[yocto] HTTP-accessible poky repo?

[Evade Flow]

I'd like to track yocto development more closely, but I'm stuck behind a
restrictive HTTP-only firewall all day at work.  Is there an official
(or unofficial-but-up-to-date), HTTP-accessible mirror of
git://git.yoctoproject.org/poky.git I can clone from?

I can create a clone on github and run some cron scripts at home to sync
it, but I'd rather not bother if there's already something like this out
there...
