For three hours on August 22, 2013, trading was halted on the Nasdaq Stock Market. Trading on the exchange stopped at 12:14 pm and resumed at 3:25 pm, with 35 minutes left of trading for the day. One week after the trading halt NASDAQ OMX credited the freeze to an overloading of the Securities Information Processor (SIP) caused by reconnection issues with the New York Stock Exchange Arca. The freeze received substantial media coverage and generated discussions on the security of increasingly technologically advanced stock exchanges. The event coined the term "flash freeze" following the earlier "flash crash" on May 6, 2010.
