Looks like rfa.org uses Speedera (see the log of finding and querying the authoritative name servers below). To quote from their web site at http://www.speedera.com/primary/Tech/Over.htm : "Speedera's highly distributed, robust network relies on a worldwide set of probes and global traffic managers to make real-time decisions to intelligently route users' requests to the best location and best server." It sounds like this is just part of Speedera's attempt to route users to the appropriate server. $ whois rfa.org ...
