CME Group Data Center Outage Disrupts Services for Over 10 Hours

According to BlockBeats, a critical data center used by the Chicago Mercantile Exchange (CME) Group experienced a service disruption lasting more than 10 hours due to overheating. The incident occurred from the evening of November 27 to the morning of November 28, local time. The data center, located in Aurora, a western suburb of Chicago, faced a cooling equipment failure, causing temperatures to rise to nearly 49 degrees Celsius, exceeding the U.S. industry standard maximum by approximately 48% and resulting in the service interruption. It remains unclear why CME Group did not activate its backup data center in the New York area. Some informed sources speculate that the reason might be the inadequate technical infrastructure at the backup site for large traders quoted by CME Group, leading them to prefer waiting for the Aurora issue to be resolved.
