Interesting article . . . but reading the article you sent closely it is not clear they were really canceled.
It says Knight's website claimed they were canceled but NASDAQ and NYSE failed to comment . . . and cause was human error by Knight . . . in the thick of it again.

The trades occurred early in the session when prices dropped by as much as 98 percent after a human processing error at Knight Capital Americas, a market maker for the ETFs.

The net asset values of the ETFs and the value of the underlying securities and shareholders were not affected, Scottrade said.

On its website, Nasdaq said it cancelled trades in FocusShares ETFs that were executed between 9:54 am and 9:56 am that were more than 10 percent away from the day’s trade before the erroneous order or the previous close if no trades occurred prior.

Nasdaq and NYSE declined to comment.

Getting to know exchange-traded funds. ... An ETF is a basket of securities, shares of which are sold on an exchange. They combine features and potential benefits of stocks, mutual funds, or bonds. Like individual stocks, ETF shares are traded throughout the day at prices that change based on supply and demand.
