I don't care what internal routing tricks are used, they are still under the *one* external route and as such subject to single points of failure and as such don't have enough independence.
It's an open recursive name server, it is free, has no SLA, and is not critical infrastructure. Besides, it is quicker / better to use your local ISP's RNS. If something goes wrong, you can fall back to OpenDNS or L3, and, of course, yell at the _company_you_are_paying_ when their stuff doesn't work. :) -- TTFN, patrick
