The data center in Los Lunas, a village south of Albuquerque, includes six buildings for data storage. Each are about the size of four football fields with “data halls” storing rows of towering servers.

Facebook on Thursday marked the opening of two of those halls in one of the data center’s buildings.

Construction that began more than two years ago at the site remains underway.

New Mexico officials in 2016 touted the data center as a much-needed boon for the area after Facebook announced it had selected Los Lunas.
