Colonial Pipeline hit by new computer problem

Colonial Pipeline, the main Gulf Coast-East Coast artery for gasoline and other petroleum products, ran into a new computer snag Tuesday as it was still recovering from a shutdown that started May 7 after a ransomware attack.

The company said the latest problem, which interrupted the system used by shippers to place requests for service, called nominations, was not a continuation of the cyberware attack that sparked panic-buying by frustrated motorists across the Southeast last week. In a statement, the company said that the problems arose from the effort to “harden” its systems to ward off future cyberattacks.
