Colonial Pipeline Restarts Operations After Cyberattack On Fuel Supply Lines

The biggest fuel pipeline in the U.S. had halted service after becoming the victim of a ransomware attack that cut off deliveries to the East Coast.

Colonial Pipeline has restarted operations after a cybersecurity attack late last week forced the 5,500-mile privately owned pipeline system to temporarily shut down, affecting the national fuel supply.  Colonial, which is the biggest fuel pipeline operator in the United States, said that it began the restart about 5 p.m. EDT on Wednesday. Energy Secretary Jennifer Granholm first announced the restoration on Twitter, saying she had just spoken to Colonial’s CEO about the decision. “Following this restart, it will take several days for the product delivery supply chain to return to normal,” Colonial said in a statement. “Some markets served by Colonial Pipeline may experience, or continue to experience, intermittent service interruptions during the start-up period. Colonial will move as much gasoline, diesel, and jet fuel as is safely possible and will continue to do so until markets return to normal.”
