Trading was frozen at 12:14:03 ET affecting several high profile companies including Apple (AAPL), Microsoft (MSFT) and Facebook (FB).
According to CNBC, the shutdown was the longest at the exchange stock market in recent history. But in spite of the glitch, NASDAQ continued taking orders.
"Nasdaq will not be canceling open orders on the book. Customers who wish to cancel their orders may do so and any customer who wishes to not participate in the re-opening should cancel their orders prior to the resumption of trading," a spokesman said during the shutdown.
The market attributed the shutdown to a UTP SIP quote dissemination issue. UTP stands for "unlisted trading privileges" and SIP stands for "securities information processor."
A previous shutdown in 1987 was attributed to wondering squirrel.
