This could be anything, either that the mirrors list is still being read, or 
that there are machines at fedoraproject.org which are on the mirrors list, and 
you got to use one of them.

Run tcpdump to (a) write to a file, (b) save a few more bytes than the default 
so you can see long strings (maybe 150?), and (c) filter the packets grabbed, 
probably by MAC address of the machine you're using.

If it still isn't clear, you can look at the captured packets with wireshark, 
which David also suggested.
