I decided not to host ArchLinux repository anymore since the server is hosting more and more services used in our university. The main problem with ArchLinux is that it is updated too frequent and it took some time to complete the whole update. Meanwhile, i can only use rsync at night because at morning until evening, the bandwidth are reserved for students and academic activities.
So, at the end, i have to end up this service for good. I have sent an email to the ArchLinux mirror mailing list to ask them to remove UKDW Repository as their ArchLinux mirror site and hopefully by tomorrow, i can delete the whole ArchLinux repository. I have removed the information on the page and also the rsync access to the packages.
