CME Data-Center Issue Hits Options, Futures Trading

"Due to a cooling issue at CyrusOne data centers, our markets are currently halted. Support is working to resolve the issue in the near term and will advise clients of Pre-Open details as soon as they are available." - https://www.cmegroup.com/ & https://x.com/CMEGroup/status/1994258309784731926

"CME's daily traded notional exceeds $1 trillion across products, equating to ~25-35% of global ETD notional in key categories like interest rates (~$10-15 trillion quarterly) and commodities. Global ETD outstanding notional was ~$100-150 trillion in 2025, with CME leading in high-liquidity benchmarks." - Grok summary

Insane that cooling in one data center can affect this much, and no more than two sentences is the only status update for almost 6 hours.

I guess we’re not getting the full Cloudflare-style post-mortem on how one chiller took down the planet’s risk market.
