According to CMTEB, the company’s dispatch centers and intervention teams operate continuously to resolve emerging issues.

They also note that initial deadlines for restoring service are estimates, given before the site is opened and the thermal galleries are uncovered. Actual completion times depend on the condition of the pipelines, which may reveal more damage than initially assessed.
