Available clues point to a data feed error. Outages at exchanges are actually not very rare, and hacking is seldom the cause.
In fact, rodents are a much more likely suspect. One of the more embarrassing Nasdaq outages occurred in 1994, when a kamikaze squirrel triggered 34 minutes of downtime. And that was the second 'rodent incident' in seven years."
