CyrusOne responds to cooling issue that halted CME trading

CyrusOne Inc. (NASDAQ: CONE) experienced a cooling system issue at its Chicago data center that caused trading to halt on the Chicago Mercantile Exchange on Friday.

The company stated it has deployed temporary cooling equipment and is working to restore full cooling capacity at the facility. CyrusOne said it is actively responding to the cooling system problem.

"Due to a cooling issue at CyrusOne data centers, our markets are currently halted," a CME spokesperson said in an emailed statement Friday morning. "Support is working to resolve the issue in the near term and will advise clients of Pre-Open details as soon as they are available."

The CME indicated it may take time for movements in affected contracts to be visible once the outage is resolved. The exchange did not specify when trading might resume.

CyrusOne operates data centers that provide critical infrastructure services to financial exchanges and other clients requiring high-availability computing environments.
