[opensuse-factory] Unavailable Tumbleweed iso downloads

Hello, I just tried to download the latest network installation iso and the link resulted in a 404 error. The normal download.opensuse.org link redirected me to the following mirror (I'm in the Netherlands): http://mirror.karneval.cz/pub/linux/opensuse/tumbleweed/iso/openSUSE-Tumblew... I tested this with both DVD and network installation for both x86_64 and i586 platforms - all result in 404 errors. Any idea why these are failing? -- Chris
