It seems that the route from download-i2 to you is going over commercial peering rather
than NCREN/I2.

For example, here is what one should get going from download-i2 to utexas.edu. See how it
exits redhat onto ncren?

You won't be able to reach the servers if the routes are incorrect. The question is,
why is the router at hop 4 sending to you via rr.com instead of ncren?

Subject: problems with download-i2
It looks like download-i2.fedoraproject.org may be having problems, I've been unable
to connect for a few days now.
