In the repository configuration file you should modify this:
vi /etc/yum.repos.d/fedora-updates.repo
Code:
[updates]
name=Fedora $releasever - $basearch - Updates
failovermethod=priority
#baseurl=http://download.fedoraproject.org/pub/fedora/linux/updates/$releasever/$basearch/
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=updates-released-f$releasever&arch=$basearch
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch
you should comment the mirrorlist and uncomment the baseurl.
if you want to pick another mirror you should check what mirror is available in the mirrorlist URL, changing $releasever for 10/11 and $basearch for i386 (or your architecture)
