Error: Cannot find a valid baseurl for repo: freshrpms

After upgrading my T43 to FC6, I added yum-fastestmirror and FreshRPMS 
release. Now while working with yum (a lot of yum list/search/info 
commands) in the past couple days I intermittently keep getting this 
error; if I try over and over again it eventually connects to something 
and rolls along.

This didn't really happen with FC5 that I can remember; is anyone else 
getting it? Any suggestions on what might be amiss on my system?

thanks,
-te
