CyrusOne

CyrusOne said it has restored stable operations at its Chicago 1 (CHI1) data center in Aurora, Illinois and installed extra redundant cooling capacity after a catastrophic cooling failure sent temperatures above 100°F. The outage late Thursday halted trading across markets for hours after CME opted not to switch to its New York backup, believing the interruption would be brief. Most services were restored Friday and the Commodity Futures Trading Commission monitored the disruption. » Plus sur finance.yahoo.com

Calpine has increased the original 190 MW power supply agreement with CyrusOne by a further 210 MW to a total of 400 MW. The agreement secures power supply, grid connection and site infrastructure for a data center under construction in Bosque County, Texas, which is expected to become operational in Q4 2026. Both companies are coordinating operating procedures and curtailment rules to ensure grid stability during supply shortages. » Plus sur de.investing.com

CyrusOne notified Aurora residents that final emergency electrical repairs will require backup generators on Aug. 22, with work expected to last up to eight hours and fewer generators in use than previous repairs. Neighbors say previous multi-day generator runs in April were excessively loud and disruptive; CyrusOne has installed a temporary sound wall, is building a 23-foot permanent wall due in September, and offered limited hotel reimbursements to affected residents. City officials, including Mayor John Laesch, are coordinating with CyrusOne on permits, timing and additional acoustic measures for rooftop chillers. » Plus sur yahoo.com
