[CentOS] Can't update CentOS 5.2

I've just installed a fresh CentOS 5.2

Now, I run "yum update" and I get:

"Could not retrieve mirrorlist
http://mirrorlist.centos.org/?release=5&arch=i386&repo=os error was
[Errno 4] IOError: <urlopen error (110, 'Connection timed out')>
Error: Cannot retrieve repository metadata (repomd.xml) for repository:
base. Please verify its path and try again"

I have Internet connection, but I cant ping mirrorlist.centos.org and
http://mirrorlist.centos.org/?release=5&arch=i386&repo=os just stalls.

Is there another "mirror list" and if so, how do I configure it ?

Any help would be appreciated.

Warm Regards,
