If any of the backends is inaccessible, this is not an obstacle for use with the redirector. For detailed information suitable for diagnostics, in addition to the summary status, the status of individual backends could also be listed there. Instead of the summary "partial", a real state could be seen. For information, the redirector uses a special page mode to find usable mirrors, where it gets a plain list of usable urls - mirrors that are not ready are not listed: https://www.trinitydesktop.org/mirrorstatus.php?mr > > What is your opinion on this idea?
