A process on download.savannah.gnu.org pulls the http://www.gnu.org/prep/FTP file and parses it in the mirror process. This process is currently producing an error due to a missing comma in one of the entries.
I don't know if there is a formal syntax for that file but it does seem to be the only entry that is missing a comma. Perhaps this could be added so as to resolve the issue without worrying too much about it? --- FTP.original 2019-01-17 23:25:48.293179717 -0700 +++ FTP 2019-01-17 23:25:50.425197797 -0700 @@ -119,7 +119,7 @@ France - https://mirror.ibcp.fr/pub/gnu/, http://mirror.ibcp.fr/pub/gnu/ France - https://ftp.igh.cnrs.fr/pub/gnu/, http://ftp.igh.cnrs.fr/pub/gnu/, ftp://ftp.igh.cnrs.fr/pub/gnu/ France - https://mirror.cyberbits.eu/gnu/, http://mirror.cyberbits.eu/gnu/ (also, mirrors alpha: https://mirror.cyberbits.eu/gnu/alpha/, http://mirror.cyberbits.eu/gnu/alpha/) -Germany - https://www.singleboersen.com/mirror/gnu/ http://www.singleboersen.com/mirror/gnu/ +Germany - https://www.singleboersen.com/mirror/gnu/, http://www.singleboersen.com/mirror/gnu/ Germany - https://mirror.bibleonline.ru/gnu/, http://mirror.bibleonline.ru/gnu/ Germany - https://www.artfiles.org/gnu.org/, http://www.artfiles.org/gnu.org/ Germany - http://ftp-stud.hs-esslingen.de/pub/Mirrors/ftp.gnu.org/, https://ftp-stud.hs-esslingen.de/pub/Mirrors/ftp.gnu.org/ Thanks!
