Colonial Pipeline has got its entire system back on track, delivering millions of gallons of fuel every hour, after a ransomware attack forced the company to shut down its network last Friday.

The company announced on Saturday that its pipeline now serves all markets including Texas, Louisiana, Mississippi, Alabama, Tennessee, Georgia, South and North Carolina, Virginia, Maryland, DC, Delaware, Pennsylvania and New Jersey.

However, fuel shortages remain widespread in many of these markets. In Washington, the country’s capital, 80% of gas stations are without fuel, according to the latest data from GasBuddy. In North Carolina, 63% of the stations are short, in Georgia and South Carolina more than 40%, and in Virginia 38%.

The cyberattack had forced the company to shut down approximately 5,500 miles of pipeline and sparked widespread fuel shortages and panic buying in some states.

Colonial carries nearly half of the east coast’s fuel supplies, including gasoline, diesel, heating oil, and jet fuel. Colonial resumed operations at around 5 p.m. ET on Wednesday, but warned that the pipeline would not be fully operational immediately.

A US official, who spoke on condition of anonymity, told NBC News Thursday that Colonial had paid cybercriminals nearly $ 5 million in ransom. It is unclear when the transaction took place.

The Department of Energy, in coordination with the FBI, the Department of Homeland Security, and the Department of Defense, led the federal response to the attack, which was carried out by a cyber criminal group called DarkSide.

Colonial said it will invest in the necessary resources to maintain safe and reliable pipeline operations.

“From the start of this incident, it was clear to us that our focus was on safely and efficiently restoring service to our pipeline system,” Colonial said in a tweet. “We achieved this through the commitment and dedication of the many members of the colonial team.”

“Our team members across the pipeline have worked safely and tirelessly around the clock to get our product lines up and running, and we are grateful for their dedicated service and professionalism during these extraordinary times,” the company said.
