CME Group Works to Restore Services After Technical Outage Shuts Markets
A cooling failure at CME Group's data center partner CyrusOne triggered a widespread systems outage late on November 27, forcing the suspension of trading across several major markets. The disruption emerged during thin post-holiday liquidity conditions, knocking Core platforms offline and leaving traders without real-time pricing access.
Critical infrastructure vulnerabilities were exposed as the outage coincided with subdued trading activity, amplifying operational risks. Market participants faced asymmetric information gaps during the blackout, with no immediate workaround for disrupted price discovery mechanisms.
