NYSE Euronext markets in Europe go temporarily dark after glitch; trading up and running now

PARIS – Trading on a number of European exchanges started about an hour late Thursday after a problem with NYSE Euronext’s systems prevented customers from placing orders.

Exchanges in Paris, Lisbon, Brussels and Amsterdam were affected by the unexplained glitch.

But NYSE Euronext spokeswoman Caroline Tourrier said all trading was normal by around 10:00 a.m. CET (0800 GMT) and that the New York exchange should not be affected when it opens.

Tourrier said the company still could not say what caused the glitch and that investigations were ongoing.
