Then I must be extremely unlucky, in that *every* time I type in 
'yum upgrade', the mirrors happen to be "still syncing".

I got this "no more mirrors to try" response to 'yum upgrade' 
multiple times on July 11 and July 12 (and now on July 13) -- in 
fact, on every 'yum upgrade' I've tried in the last several days.

I looked with a browser inside one of the attempted mirror 
repositories (fedora/updates/11/i386) - and yes, the package level 
that my 'yum upgrade' was looking for is *not* there.  The most 
recent timestamp for any of the packages there says July 9.  I wish 
that repository would get a move on with its syncing.
