CME Group Suffers 10-Hour Outage at Aurora Data Center After Cooling Failure; New York Backup Data Center Not Activated

COINOTAG News reports that, from the night of November 27 into November 28, a critical CME Group data center in Aurora, Illinois, endured a more than ten-hour outage caused by a cooling system failure. Temperatures rose toward 49°C, surpassing the industry limit of about 48°C and triggering disruptions to market data feeds and order routing used by crypto desks and clearing operations.

CME Group has not publicly disclosed why the New York backup data center was not activated; the reasons remain unconfirmed. The episode underscores the complexities of cross-region failover and the potential impact on liquidity and price discovery amid crypto trading activity.

From a market-infrastructure perspective, the outage highlights the need for robust cooling, redundant pathways, and transparent incident timelines to protect risk controls and investor confidence in crypto markets.
