The data center that supports CME Group Inc., one of the world’s largest derivatives exchanges, said it has bolstered its backup cooling capacity after overheating sparked a catastrophic 10-hour outage that roiled world markets on Friday.
CyrusOne — which owns the facility in the suburban town of Aurora, Illinois, some 50 miles (80 kilometers) from Chicago — said it had restored “stable and secure” operations and that it had installed “additional redundancy to the cooling systems,” according to a statement to Bloomberg News on Sunday. The data center serves as the hub for trillions of dollars of derivatives that change hands each day across equity, currency, bond and commodity markets globally.
