<p>I want to highlight one (hopefully) entertaining point. There
is evidence in Geoff's and Tony's graphs of when all of this
happened because there was a drop in the number of routes in
1994. If you squint, you can see it <a
href="https://bgp.potaroo.net/">here</a> just at the lower
left-hand side of the graph. It's really funny to me because
the scale of that graph has changed <b>dramatically</b> –
bordering on two orders of magnitude. At the time the dip was a
substantial percentage of the routes at the time.</p>
<p>I will also point out that even though endpoints by-and-large
were not involved, keeping the routers from falling down
nevertheless was the result of an enormous effort and
collaboration between researchers, developers, and operators,
who I doubt very much would ever want to repeat that sort of
experience.<br>
