In recent years there was a lot of negative talk of how the exchanges where becoming too 'fragmented' (decentralized). Today the NYSE is just one of 9 major exchanges  in the US where you can buy and sell securities.  This was not always the case.

Today's events show how 'decentralization' can be a good thing.  Trading continued on other exchanges with only a slight reduction in volume.

As is always the case, we tech enthusiasts already know and use this.  In the world of Crypto there are hundreds of exchanges, and one going down usually goes unnoticed.
