An electrical fire on Sunday at a data center of the New York Stock Exchange in Mahwah, New Jersey, affected communications connectivity to 58 trading firms, but the exchange expects "completely normal operations" for Monday's market open.
The electrical fire was in a single computer cabinet at the Mahwah data center, and was quickly extinguished, said Ray Pellecchia, a spokesman for NYSE Euronext, which owns the exchange.

The incident did not result in any injuries, he said.
The traders whose communications were affected have been notified that all systems are being tested, and that normal operations are expected for the open on Monday, Pellecchia said.
"We are grateful for the quick and thorough response by the Mahwah Fire and Police Departments as well as our Mahwah data center staff," he said.
