Never mind, I found them. They are at an obvious place, which I missed before. Nevertheless, it turns out that of all the CLFS advertized mirror sites, that is,
ftp://ftp.osuosl.org/pub/clfs/ - FTP - Corvallis, Oregon, USA
http://ftp.osuosl.org/pub/clfs/ - HTTP - Corvallis, Oregon, USA
ftp://ftp.cross-lfs.org/pub/clfs/ - FTP - Los Angeles, California, USA
http://ftp.cross-lfs.org/pub/clfs/ - HTTP - Los Angeles, California, USA
only
http://ftp.osuosl.org/pub/clfs/clfs-packages/1.1.0/
does actually mirror anything. At least right now.
