NYSE suffers 'cosmetic problem' on data screens

A "cosmetic problem" affected data displays at the New York Stock Exchange on Thursday.

The issues did not seem to disrupt trading. Many screens, which typically show quotes and other information, displayed NYSE logos. Thomson Reuters, which provides the data for the displays, said it was affected by issues at a New Jersey data center, which "interrupted service to a small number of clients."

"We are communicating proactively with affected clients and the contractor to ensure services are resumed as quickly as possible," the statement said.

A chilled water pipe failed, affecting the cooling in a New Jersey facility owned by CenturyLink.

"Customers have been notified, and out of an abundance of caution, some CenturyLink clients have chosen to temporarily shut down non-mission critical equipment," CenturyLink said in a statement.

An Investment Technology Group dark pool, which handles more than 300,000 stock trades per week, was taken offline because of the problem, Dow Jones reported.

CNBC's Bob Pisani and Ryan Ruggiero contributed reporting.
