Having worked at Omniture (now part of Adobe) in a previous life, I can vouch for this.
Unfortunately, I don't have enough information to be able to make an educated guess as to why we're seeing an increase in referrals from
fedoraproject.org to
redhat.com. As Paul said, the http logs from Red Hat IT are probably going to be the most valuable in helping us find out several key pieces of information: 1) Which page(s) on
www.fedoraproject.org are referring people to
redhat.com, and 2) Are there any similarities re: User Agent on those redirects and 3) are all the redirects going to the same page on
www.redhat.com and 4) Is there any variability in IP addresses? Times of day?
While Omniture's SiteCatalyst should be able to give you some of this information, I'd love to see someone grab the HTTP logs from the server and do some more focuses analysis.
