Overview
- CyrusOne said its Chicago 1 facility in Aurora is stable and now has additional cooling redundancy following last week’s failure.
- A late-Thursday cooling-system malfunction pushed temperatures above 100°F and knocked out CME’s futures and options trading.
- Trading halted across assets from Asia through Europe and the U.S., with most CME operations restored by Friday afternoon U.S. time.
- CME did not switch to its New York–area backup because initial information suggested a brief outage, and it restarted the matching engine in Aurora, according to reporting.
- CME relies on the Aurora site it sold to CyrusOne in 2016, and the CFTC said it was monitoring markets during the disruption.
