To be clear, mirrors.openembedded.org is a "last resort" type of mirror
(eg the tinylogin case) whereas autobuilder.yoctoproject.org and the
angstrom mirrors are complete (modulo fetch2 git issues, on the angstrom
side) mirrors.

Both have their uses and I think for oe-core we want just the former (so
that when tzcode/tzdata get their weekly upgrade, we know) while poky,
angstrom, etc, etc, will continue to want what they have now.
