CyrusOne Working to Respond to Cooling Issue Behind CME Outage
By Adria Calatayud and Kimberley KaoData-center operator CyrusOne said it is actively responding to an issue at a data center in the Chicago area behind the CME outage, with teams working to restore normal operations as quickly as possible.The company said Friday that the glitch was caused by a chiller plant failure affecting multiple cooling units at a data center in the Chicago area.The tech outage halted trading of futures and options on the Chicago Mercantile Exchange for hours on Friday, disrupting some of the world's most liquid futures markets across asset classes including U.S. stocks and Treasurys."Our engineering teams, along with specialized mechanical contractors, are on-site working to restore full cooling capacity," a CyrusOne spokesperson said. "We have successfully restarted several chillers at limited capacity and have deployed temporary cooling equipment to supplement our permanent systems."A CME Group spokesperson said separately that its BrokerTec EU markets are open and trading, with all others halted due to the data center cooling issue at CyrusOne.CyrusOne, which operates dozens of data centers worldwide, owns the main electronic-trading hub for CME's markets in Aurora, Ill., outside of Chicago. The privately held firm was acquired for about $15 billion by buyout firms KKR and Global Infrastructure Partners in 2022.Write to Adria Calatayud at [email protected] and to Kimberley Kao at [email protected]
