The main fuel line to the U.S. east coast was closed on Friday after the pipeline operator was hit by a cyber attack.
The attack on the Colonial Pipeline, which spans 5,500 miles and supplies nearly half of the fuel used on the East Coast, affected some of the company’s computer systems. Colonial said in a statement Friday that it hired an unidentified third-party cybersecurity company to investigate the incident and contacted law enforcement and other federal agencies.
The company said the process is underway to restore service and return to normal operation. The FBI, the Department of Energy and the Federal Energy Regulatory Commission could not immediately be reached for comment.
