Thanks for your suggestions.
What's puzzling is that the Windows laptop
(actually it is the same laptop running Windows XP in place of Fedora)
goes through the same CentOS box to the internet.

I don't really understand how the mirrorlist URL is interpreted.
I notice that under Windows, if I "ping mirrors.fedoraproject.org"
and then substitute IP address I get in http://<IP address>/releases.txt
then again the file is not found.

Incidentally, I've been running the CentOS machine for a couple of years,
and never had any problem like this with any other URL.

I'm sure the basic cause of my misunderstanding
is that I don't understand what a "mirrorlist" is,
or rather how it is interpreted.

But I'll see if tcpdump, or something like that, will tell me anything.
