- CME Group’s 10-hour trading halt linked to data center error.
- CyrusOne blamed for the failure in cooling systems.
- Global markets and derivatives trading substantially impacted.
CME Group faced a 10-hour trading halt last Friday due to a data center outage at CyrusOne in Aurora, Illinois, attributed to human error exacerbating the cooling system failure.
This incident underscores the risks of high reliance on a single data center, impacting global market operations across multiple asset classes, including cryptocurrency derivatives.
CME Trading Halt Caused by Data Center Failure
CME Group’s operations were disrupted by a cooling system failure at CyrusOne’s Aurora data center, attributed to human error. The incident caused a halt in multi-market trading for over 10 hours, affecting crucial futures markets. CME relies heavily on the facility, which hosts its primary trading engines.
Eric Schwartz, CEO, CyrusOne, stated, “Onsite staff and contractors at the facility in Aurora, Illinois, failed to follow standard procedures for draining cooling towers ahead of freezing temperatures.” The incident highlights the necessity for robust disaster recovery strategies to manage unforeseen technical failures.
Key figures at CyrusOne, including CEO Eric Schwartz, were dispatched for remediation efforts. A CME statement to Bloomberg acknowledged the significant impact on global clients. Despite additional personnel efforts, this incident has prompted discussions about data center reliance and operational risks.
Market Reactions and Future Risk Mitigation Strategies
Did you know? The last significant CME market disruption occurred in 2013 due to a cyber intrusion, underscoring single-point-of-failure risks akin to the recent cooling facility issues.
