There's a new column on the IA Upload
https://tools.wmflabs.org/ia-upload/ log to permit the download of the
DjVu files, for those files that are failing to upload to Commons. This
is just a work-around until we have larger-file uploading fixed (which
should be soon, see
https://phabricator.wikimedia.org/T175680 for more
info).
