mirrors inconsistent?

I tried to download Tumbleweed offline installation image. First I got redirected to https://ams.edge.kernel.org/opensuse/tumbleweed/iso/openSUSE-Tumbleweed-DVD-... which gave me 404. Then I tried to pick another url from mirror list. http://suse.uni-leipzig.de/pub/ftp.opensuse.org/opensuse/tumbleweed/iso/open... also gave me 404. Third attempt at https://ftp.uni-bayreuth.de/linux/opensuse/tumbleweed/iso/openSUSE-Tumblewee... gives me sweet bytes.
