I'm not sure this is the right place to report this, but here goes.
When I try to download any of the LXDE or XFCE spins of Fedora 15, from http://fedoraproject.org/en/get-fedora-options, the URI points to http://download.fedoraproject.org/pub/alt/spins/linux/releases/15/Spins/... All these get redirected (for me, anyway) to http://archive.nl.eu.kernel.org/fedora-alt/spins/linux/releases/15/Spins/... However, archive.nl.eu.kernel.org is currently not resolvable. After a 1 minute timeout the "host" program tells me: ;; connection timed out; no servers could be reached
It is not easy to find an alternative direct download link.
