This happens every few days for multiple hours at a time. This would indicate a
problem with the mirrors in this region.

It appears at least that http://mirror.telkomuniversity.ac.id has not been
updated in multiple days, and http://ftp-srv2.kddilabs.jp/ is more than 1 month
out of date.

This happens frequently, to the point that every few days I'm unable to update
or install packages on opensuse tumbleweed from Australia due to the mirrors
being in this state.

Thanks,
