Where were you in 1969? It practically happened! Actually, something worse happened that year. The whole Manhattan business district network went into congestion collapse. I forget which book it was written up in, but briefly, NYTel was trying to milk every last ounce out of its COs, and was installing 1ESSs. Nobody had really seen how a 1ESS works in severe real-world overload conditions. A crossbar goes down more gently, they found out! Also, the stock market was booming (lots of calls) and the state had just allowed welfare recipients to have phones (instant demand) and you can guess what happened. It took weeks to get unglued. And a lesson was learned by all. (Well, almost all.)
