yum updating FAST!!!
Hopefully some newbies (like myself) will find this useful.
I contacted my ISP and asked if they had a mirror for performing Linux updates (in my case Fedora Core 1). They said they did and provided me the url.
I modified the yum.conf file to point to the location provided by my ISP and the updates are flying across the wire!!!
I never would have found the updates area on my ISP if I hadn't contacted them.
Maybe a call to your ISP will help.
