Nasdaq said it
halted trading for three hours Thursday after a "connectivity issue
between an exchange participant" and a system that disseminates all
stock prices for the industry.
According to Nasdaq, the problem "led to a degradation in the ability of the SIP to disseminate consolidated quotes and trades."
Nasdaq did not identify which exchange had the issue connecting with the Securities Information Processor, also known as SIP.
In its statement, it did say the "cause of the issue has been identified and addressed."

Nasdaq: Identified & addressed 'connectivity issue'
CNBC's Josh Lipton reports the Nasdaq has identified and addressed a connectivity issue in regards to today's trading glitch.
Nasdaq said once it became aware of the
problem, it halted trading in all Nasdaq-listed securities to "protect
the integrity of the markets."
The SIP's technical issues were resolved in the first 30 minutes, Nasdaq added. The remaining time was needed to coordinate with other exchanges, regulators and market participants for an "orderly re-opening" of trading.
Trading resumed at 3:25 pm ET after the longest shutdown at the exchange in recent memory. It halted trading in such high-profile companies such as Apple, Microsoft and Facebook.
Despite the freeze, Nasdaq said that it would not cancel orders.

SEC Chair Mary Jo White said in a separate statement the "serious" interruption underlines the need to address "technological vulnerabilities."
The exchange closed at its normal time of 4 pm ET. Despite the troubles, stocks closed slightly up for the day.

There were reports Thursday morning that NYSE Euronext was telling traders its electronic exchange Arca was having technical issues with some Nasdaq-listed stocks. Nasdaq stopped routing orders to Arca temporarily, but reportedly the issues were resolved before Nasdaq halted all trading.
Nasdaq officials would not comment when asked if the "exchange participant" that had the "connectivity issue" was Arca. The NYSE also had no comment.
Once Nasdaq resumed trading, there were some technical issues when Arca went to reconnect, an NYSE spokesman said. He made the comment in response to a question before the latest Nasdaq statement.

Nasdaq 'flash freeze' fallout
A major technical glitch halted the Nasdaq this afternoon. The "Fast Money" traders and CNBC's Bertha Coombs and Bob Pisani.
The shutdown brought sometimes vehement criticism from across Wall Street.
"This is such an embarrassment to the entire financial community. To have the Nasdaq go down as it has; to be down three hours—it's one thing to be down for five minutes—to be down for three hours is absolutely inexcusable," said Dennis Gartman, editor and publisher of The Gartman Letter.

"It reminds me of sitting at the US Airways terminal and hearing nothing from nobody and you're getting angrier by the hour," he said.
Former SEC chairman Harvey Pitt told CNBC: "It looked like Nasdaq was clueless about how to deal with this emergency."
"Nasdaq has, in my view, serious issues and there are two particular problems here. The first is, is there technology up to the task. That's number one and then the second is, that when technology goes bad, do they have an established crisis management program?," Pitt said.

Within an hour of the shutdown starting, the Nasdaq options markets issued a "system update" saying they were recommending firms route all open orders elsewhere. An average of 1.6 billion shares have been traded on the Nasdaq every day this August, according to statistics from Sandler O'Neill.

The New York Stock Exchange halted
trading in all Nasdaq securities at its request and canceled orders. The
NYSE otherwise declined comment. The CME said it saw 'no impact' from
Nasdaq's trading halt.

"If I was back in the days of 10 years ago
managing 300 traders I'd put the directive out to every one of them 'we
don't put any orders in at the open' ... no one trades for 60 minutes,"
said Joe Terranova, chief market strategist for Virtus Investment
Partners and a CNBC contributor.
The shutdown of exchanges without an external crisis is rare, but a stray squirrel shut down the Nasdaq in 1987, according to the New York Times.
