Nanosecond Trading Could Make Markets Go Haywire
http://www.wired.com/wiredscience/2012/02/high-speed-trading/

"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.
