http://www.cs.cornell.edu/People/egs/beehive/codons.php Lately, we have been using CoDoNS to support electoral-vote.com, Andy Tannenbaum's highly popular election tracking site that has come under DoS attacks. You can take a peek at an internal snapshot of the system here: http://beehive.systems.cs.cornell.edu/codons-noc/ An average DNS record is backed by ~2 nameservers, where both servers are in the same ISP. Andy's site is now backed by a whole P2P network at about 70+ points of presence. This is the sort of thing a P2P architecture does well. If you are interested in how to use proactive replication to handle a demanding Zipf-like workload, the Beehive paper at NSDI 2004 has the details. Gün & Rama & Ilya.
