CyrusOne Halts Bond Sale After Data-Center Failure Cripples CME

Goldman Sachs Group Inc. has paused a planned $1.3 billion mortgage-bond sale for CyrusOne, the data-center operator that supports CME Group Inc., after a major outage that hit one of the world’s largest derivatives exchanges.

The bank had been managing what would have been CyrusOne’s largest-ever commercial mortgage bond sale, with early feedback due on Nov. 25, according to people familiar with the matter. Just days later, CME’s global markets went out for more than 10 hours due to failure in the cooling system at its facility in Aurora, Illinois, which serves as the hub for trillions of dollars of derivatives traded each day.
