For such an important software, why is it so difficult to get yum
update for Centos 5* without an official resolution from
fedoraproject.org for this common embarrassing issue littering the
internet.
yum update

Could not retrieve mirrorlist
http://mirrors.fedoraproject.org/mirrorlist?repo=epel-5&arch=i386
Works here if I try it:
$ curl "http://mirrors.fedoraproject.org/mirrorlist?repo=epel-5&arch=i386"
# repo = epel-5 arch = i386 country = DE
