Nasdaq Resolves Connectivity Issue That Hit Some Customers

The problem affected a large share of clients that buy dedicated port servers in the Nasdaq data center.

Ksenia Galouchko and Ryan Vlastelica (Bloomberg) -- Nasdaq said it has resolved an issue with connectivity to the exchange affecting some customers.

“The earlier issue with connectivity to the exchange for a subset of OUCH and FLITE ports has been resolved,” the bourse said in a statement on its website.

The problem affected a large share of OUCH clients, the exchange operator said earlier, referring to a service that provides clients with their own dedicated port server in the Nasdaq Data Center.

The Nasdaq is the latest in a string of global exchanges to report operational issues. Australia’s stock exchange in November was forced to halt trading because of a technical glitch, while trading on the Tokyo Stock Exchange’s cash equity market was halted for an entire day on Oct. 1, an unprecedented shutdown. Also in October, Euronext NV shuttered markets for three hours, citing a “middleware” issue for the crash.

Futures contracts on major U.S. equity indexes tumbled as a new strain of coronavirus fueled risk aversion. S&P 500 futures slumped as much as 3% in early trading Monday, while stocks in Europe also sank.
