on the page: http://ftp2.de.debian.org/debian/
directly under "Current Releases" it is said that the Release "Debian 5.0.10, or lenny <http://ftp2.de.debian.org/debian/dists/oldstable/>" would be available on this main site, but the link ( http://ftp2.de.debian.org/debian/dists/oldstable/ ) results in "Not Found" .. because it seems to have moved to the archive. this seems to be true not only for ftp2.DE.debian.org but for others as well ( AU, BE, BR ..)
