Jinse Finance reported that from the evening of November 27 to the morning of November 28 local time, a key data center used by the Chicago Mercantile Exchange Group in the United States suspended service for more than 10 hours due to overheating. It is reported that this critical data center is located in Aurora, a western suburb of Chicago. After the air conditioning equipment failed, the temperature in the data center rose to nearly 49 degrees Celsius, about 48% higher than the maximum temperature stipulated 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 sources speculate that the possible reason is that major traders quoted on CME lack sufficient technical infrastructure at the backup data center, and therefore prefer to wait for the Aurora outage to be resolved.
