Description of problem:
One of the mirror site in Taiwan, twaren.net, has been out of sync for some weeks. For now it does not have cauldron media, and mageia 2 x86-64 is incomplete. But this mirror site is still available as package media for Cauldron/mageia2 x86-64 users. 

Version-Release number of selected component (if applicable):
Cauldron i586/x86-64
Mageia 2 x86-64

How reproducible:
Probably temporarily
(I already informed twaren admin sync issue, might take a few days or weeks to recover)

Steps to Reproduce:
1.Go to this URL and search for mirror of specified version-arch
http://mirrors.mageia.org/distrib?version=cauldron&arch=x86_64
or
1.Install a Cauldron or Mageia 2 x86-64 PC.
2.Try add specified media in Mageia Control Center.
3.Twaren.net is available for select, but it will fail as the media is incomplete.
