Nathaniel Popper, New York Times:
Trading on the New York Stock Exchange was shut down for hours on Wednesday as the exchange tried to cope with what appeared to be a technical glitch, rather than an attack.
The first technical problems appeared soon after the opening bell rang at 9:30 a.m. on Wednesday, when orders for several smaller stocks failed to go through, Mr. Costa and another trader on the floor said.
These systems never go down, so I bet the inside story of this would be relatively mundane, if not for its context. Nevertheless, I’d love to know the technical details on this one.
