I'm not sure a graph would be the best representation of this data. The interesting questions to me are: - Compare Failure Levels - What is the overall level of UDP failure? - What is the overall level of UDP+EDNS0 failure? - What is the overall level of TCP failure? - Exploring the differences in the ecosystem - Is there a statistical difference in the failure rate between IPv4 and IPv6? (Are we getting better or worse) - Is there a statistical difference in the failure rate between two different root servers? (Does the root server deployment model matter) - What is the difference in response time of TCP queries compared to UDP queries? (What's the penalty to fall back to TCP) -- Leo Bicknell - bicknell at ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ -------------- next part -------------- A non-text attachment was scrubbed...
