Colonial Pipeline said Saturday that it returned its service to "normal operations."
The company began a restart of pipeline operations at 5 p.m. Wednesday.
The company, which provides nearly half of all fuel on the East Coast, was the victim of a cyberattack.
Colonial Pipeline on Saturday announced that it had returned to "normal operations" days after it restarted its pipeline following a cyberattack that resulted in disruptions across the East Coast.
The company made the announcement on Twitter Saturday at 7:30 a.m. It had restarted the pipeline at 5 p.m. on Wednesday.
"Since this incident began, we have been clear that our focus was on the safe and efficient restoration of service to our pipeline system," Colonial Pipeline said in a tweet. "That is what we have achieved through the commitment and dedication of the many Colonial team members."
It continued: "Our team members across the pipeline worked safely and tirelessly around the clock to get our lines up and running, and we are grateful for their dedicated service and professionalism during these extraordinary times."
The Colonial Pipeline is the largest pipeline of refined oil products in the US. It transports more than 45% of all fuel used on the East Coast to more than 50 million people from New York to Texas.
The Wall Street Journal reported Friday that DarkSide, the hacker group that took responsibility for the ransomware attack, said it planned to disband following pressure from the US and investigations by law enforcement agencies.
Bloomberg first reported that DarkSide received approximately $5 million in untraceable cryptocurrency from Colonial. According to the Bloomberg report, the company paid the ransom within hours of the May 7 attack.
The attack caused governors in several states to declare states of emergency as residents panic bought gasoline and caused gas stations to hike up prices and run out of fuel. Experts said it could take days to weeks for a return to normal in the affected states.
