As pragmatic as that algorithm seems, it doesn't fare well when root servers are handing out incorrect information. I realize that is beyond your control, but I'm wondering if it is possible to take corrective measures when something like this happens so that QDNS minimizes the impact. Currently, the best I can do is just reset the cache repeatedly. > You might be interested in checking the following article, relating > to the root server problem you experienced: > > http://www2.pageplop.com/pageplop/serverstatus.html Funny you should mention that. I'm the SysAdmin at PagePlop and I helped write the article (my email is also mikey@pageplop.com). In fact, QDNS's selection algorithm is what caused us to first notice that the H root server was acting up. Michael Sullivan mikey@pageplanet.com
