Due to an error when setting up a new primary mirror of the kernel.org website and making changes to the infrastructure that ensures the operation of primary and secondary mirrors, all data in the hierarchy was deleted on existing mirrors kernel.org/pub/, which, among other things, stored archives with code for all kernel releases, patches and files with lists of changes. The reference data was not affected, only the copies on the mirrors were deleted, which led to an empty directory being shown when accessing kernel.org/pub/. Currently work is underway to restore the contents of the mirrors.
