News category : Market Structure and Financial Stability Events

Following a disruptive outage that froze trading on CME electronic platforms, data center operator CyrusOne announced it had bolstered backup cooling capacity at its affected Chicago-area facility. The earlier cooling malfunction had forced CME to suspend futures and options trading across multiple asset classes for several hours, interrupting price discovery and hedging. The incident prompted urgent industry and regulatory discussions about contingency planning and single-point dependency risk. While CyrusOne's remedial steps aim to reduce recurrence, the episode prompted market participants to reassess operational redundancies and the implications for intraday liquidity during critical market windows.
