CyrusOne Data Center Outage Disrupts CME Group Operations for Over 10 Hours

According to ChainCatcher, CyrusOne has confirmed that its data center in Aurora, Illinois, experienced a significant outage due to human error, causing a disruption in the markets operated by CME Group for more than 10 hours. The incident occurred when on-site staff and contractors failed to follow standard procedures to drain the cooling towers before the onset of cold weather. This oversight led to an overload of the cooling system and a subsequent rise in temperature. CyrusOne is jointly owned by KKR & Co. and Global Infrastructure Partners. The event has raised concerns about the reliability of financial market infrastructure. Previously, it was reported that on November 28, the Chicago Mercantile Exchange (CME Group) had to suspend commodity futures trading.
