Colonial Pipeline, the largest U.S. refined products pipeline operator, has halted all operations after it fell victim to a cybersecurity attack on Friday.
Colonial connects Gulf Coast refineries with markets across the southern and eastern United States through about 5,500 miles of its pipeline system, delivering gasoline, diesel, jet fuel and other refined products.
Any prolonged outage on the line can lead to major disruptions and a spike in pump prices across the U.S. East Coast, which largely relies on the system for its supplies.
