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.

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.
