Ironically after writing a blog post earlier today commenting on how ISPs are not the best organization to handle DNS because it is not their core competency, AT&T suffered a significant DNS outage that affected many customers across the United States for many hours. Network World has a few more details as does ComputerWorld.
AT&T did not release any further details, but this only reinforces our belief that ISPs should not be your managed DNS provider. Because DNS is such a critical part of the Internet, you should trust your DNS to organizations who specialize in it.
