Since, [as I explained, and was supposed by the poster], there is "some kind of load balancing going on", and also since implementors of anycast caches have posted questions and explained their purposes [which could be seen as "load balancing"], this is a likely explanation. It may not be the only explanation: e.g. they could be restarting their nameservers every thirty seconds. But "anycast loadbalancing" of a caching server is probably the most likely.
All fine and good. But nowhere in your long paragraph do you actually address Steinar's question, which is "What does this rant have to do with *ignoring* *DNS* *TTL*?"
Try actually reading the long paragraph. It starts with the interesting sentence 'The data he showed isn't necessarilly "ignoring ttl".', and I then explain why that is. -- Av8 Internet Prepared to pay a premium for better service? www.av8.net faster, more reliable, better service 617 344 9000
