Thanks for notifying us, but we do not actually need your IP since you
are only a tier 2 mirror. You are syncing from a tier 1 mirror, which
provides public rsync access.

We listed a different subdomain here (linux instead of archlinux). I don't
know if it matters, but I've updated our list. We now list this URL:
rsync://archlinux.cs.nctu.edu.tw/archlinux/
