I did say significant…not brilliant :)

Still, it’s possible that Valdis is correct, something got changed that wasn’t easy to undo. Might be a combination of network/software changes that will require significant overnight downtime.

I think you are over estimating the technical resources at NYSE.

Given that the technical resources at the NYSE are significant and the lengthy duration of the outage, I believe this is more serious than is being reported. OTOH, the fact that the market is now mostly decentralized and instruments are multiply listed, the impact of the NYSE is much less serious than it used to be.
