The gas has been shut off for hundreds in Willimantic as Eversource deals with a service issue.
A third-party contractor was doing work on a gasline when air got into the line. Air in a gasline could blow out pilot lights in homes. Out of caution, Eversouce turned off the gasline to address the problem.
Eversource said they have 50 employees going door-to-door in order to fix the issue.
About 250 customers will be without gas for most of the night, Eversource said, but they will have crews working on repairs all night.
Customers should expect an update from Eversource in the morning about what to expect when the gas is turned back on.
