I uploaded coreutils several hours ago, and the http://ftpmirror.gnu.org... URL that went into my announcement template still is not yet valid. At least not for the mirror(s) I've been getting. I manually changed it to the canonical URL.
Note that this works fine: http://ftp.gnu.org/gnu/coreutils/coreutils-8.2.tar.gz.sig But this does not: http://ftpmirror.gnu.org/coreutils/coreutils-8.2.tar.gz.sig I made a note of one slow-to-update mirror: ftp://sunsite.cnlab-switch.ch/mirror/gnu/coreutils/coreutils-8.2.tar.gz.sig
