Failures almost never have a single cause.

Transport networks are never perfect, i.e. delays, dropped packets, data
corruption, etc. They may be contributing factors, or a combination of
rare events.  The hard question that SEC and the industry has been 
wrestling with is "Why?" not so much "How?"

The apparent condititions didn't change, but the system reacted 
differently during those seconds.  Why?  What was different?
