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.
Where has Level 3 ever claimed that these servers were ever for *external* use? As a Level 3 customer who uses these servers, I'm seeing multiple *internal* routes to these servers. Of course, if 4/8 disappears from the global routing tables then Level 3 has a bit bigger problem than their DNS resolvers not being accessible from non-customers. I'd also be interested in knowing where you consider the "single points of failure" for their announcement of 4/8 is, but that's probably for another thread... Scott.
