DNS timeline

Since it appears DNS goofiness is about to return, I put together a timeline of significant events that affected DNS service technically over the last 20 years. http://www.donelan.com/dnstimeline.html In comparison with other utilities, DNS performs about average. AT&T's telephone network had two major nationewide failures in the last 20 years. Several electrical grids have failed, including the grid covering the Western States due to a single tall tree. All the root servers have been down once, and there have been a couple of instances of zone files being truncated in the last 20 years. Not perfect, but amazingly robust for a technology operated by humans.
