= bug description = Trying to download Fedora 25 alpha from https://getfedora.org/en/workstation/prerelease/ download button redirects to https://mirrors.uni-ruse.bg/fedora/linux/releases/test/25_Alpha/Workstation/x86_64/iso/Fedora-Workstation-Live-x86_64-25_Alpha-2.iso which gives 404.
= bug analysis = This mirror seems to skip test directory as everything else is there.
= fix recommendation = Either ask the mirror to be full one or somehow exclude it from redirects to "test" directory. It would be nice to allow picking a mirror manually in such cases too.
Thanks for the bug report. This was a "configuration" error in the mirror entry in our database.
There is a checkbox called "Always up to date" which nobody should actually use. This mirror had it enabled for the "Fedora Linux" category. I disabled it and now the mirror should no longer be offered for that particular file.
As this should not be used by most mirrors I opened a bug to get it fixed: https://github.com/fedora-infra/mirrormanager2/issues/186
Seems to be fixed now that I removed the "Always up to date".
