"Below the 950-millisecond level, where computerized trading occurs so
quickly that human traders can't even react, no fewer than 18,520
crashes and spikes occurred."

Anyone who has managed a network knows that when you look at your
MRTG/Cacti graphs at 5min, 10min ,15min intervals - all looks well. 
Start looking at 1sec intervals and you will see spikes that hit 100% of
capacity - even on networks running at 25% average utilization.

I guess trading and networking do have many unseen similarities.
