[Data Center Overheating Causes CME Trading Halt for Over 10 Hours, Backup Data Center Not Activated] According to a report by Jinse Finance, from the evening of November 27 to the morning of November 28 local time, a critical data center used by the Chicago Mercantile Exchange Group (CME) was out of service for over 10 hours due to overheating. It is reported that this critical data center is located in Aurora, a western suburb of Chicago. After a cooling equipment failure, the temperature in the data center rose to nearly 49 degrees Celsius, approximately 48% higher than the maximum temperature allowed by U.S. industry regulations, resulting in the service interruption. It is currently unclear why CME did not activate its backup data center in the New York area. Some insiders speculate that the possible reason is that the technical infrastructure for large traders quoted by CME is insufficient at the backup data center, making them more willing to wait for the Aurora issue to be resolved.
