Map of dry gas stations impacted by cyberattack

According to user-reported data on the app GasBuddy, more than 17,000 gas stations across southeastern states were dry Thursday morning as panic-buying exacerbated shortages following a cyberattack that forced Colonial Pipeline offline last week. Colonial Pipeline said Wednesday evening that it has launched the restart of operations, but that the process would take several days.

High rates of outages remained most concentrated in the Carolinas, Virginia and Georgia. More than 70 percent of gas stations in North Carolina were out of gas Thursday morning, according to GasBuddy.
