On https://wiki.parabola.nu/Get_Parabola#Preview.2FBeta_Releases the SHA512SUM links do not work. First one links to https://repomirror.parabola.nu/iso-beta/systemd-lxde-2017.10.04/SHA512SUM and is a 404.

Additionally, would it not be better to not link to a mirror but have the checksums hosted on a central, trustworthy, maybe independent host?
