If you are attempting to update your AOSC OS, or have already experienced trouble downloading packages (wrong sizes and checksums, etc.) - we are aware of this issue, and are working double time to resolve this issue. We have just finished up our (long overdue) Winter update wave, and moving ~10,000 packages triggered some obscure bugs in our package scanning toolkit, p-vector.

• TL;DR: we are sorry, and are trying our best to get our repository back in normal order.
• To our mirror maintainers, we have terminated our rsync service 15 minutes before this news, and this should explain why the syncing jobs are failing.
