Hello there, The pandemonium.tiscali.de mirror, which I have maintained some time ago, is going to be shut down in October (I think - I don't work at Tiscali anymore, but they asked me to do them a favor of canceling all mirrors).
Thanks for letting us know and helping Gentoo with a mirror. I've removed the mirror from our listings.
