Colonial Pipeline announced Tuesday that its internal servers were experiencing “intermittent disruptions,” but stressed the problem was separate from the devastating ransomware attack that disrupted operations earlier this month.

“Our internal server that runs our nomination system experienced intermittent disruptions this morning due to some of the hardening efforts that are ongoing and part of our restoration process,” the company tweeted. “These issues were not related to the ransomware or any type of reinfection.”

Colonial Pipeline, which supplies about 45 percent of the East Coast’s fuel supply, noted that it was working to resolve the disruptions to the nomination system, which allows pipelines to schedule gas deliveries for customers.

“We are working diligently to bring our nomination system back online and will continue to keep our shippers updated,” the company tweeted. “The Colonial Pipeline system continues to deliver refined products as nominated by our shippers.”
