A cooling system failure at a CyrusOne data center disrupted CME Group operations, halting most markets while BrokerTec EU resumed trading.
On November 28, CME Group reported that BrokerTec EU markets had reopened, but most other markets remained suspended due to a cooling system failure at a CyrusOne data center. The halt affected commodity futures and cryptocurrency futures for Bitcoin, Ethereum, and Solana. While some operations resumed in Europe, key derivatives markets, including those for major cryptocurrencies, remain offline.
