Leap 16.0 download URL returns 404

Hi, I've tried to download Leap 16.0 prealpha from page [1]. But downloading from section "Intel or AMD 64-bit desktops, laptops, and servers (x86_64)" [2] returns 404 error: "Resource is no longer available". Opening parent directory [3] shows it as empty. Mirror list returns 404 too. Where I could get Leap 16 for testing it? 1. https://get.opensuse.org/leap/16.0/#download 2. https://download.opensuse.org/distribution/leap/16.0/installer/iso/agama-ins... 3. https://download.opensuse.org/distribution/leap/16.0/installer/iso/
