 Before discussing the network infrastructure used for the Rubin Observatory, it is important to understand the conditions under which the Vera C. Rubin Observatory—and most observatories worldwide—operate.

 At Rubin Observatory, we have multiple operational sites. There are two sites in La Serena, one in Tucson, and a data center at Stanford. However, the most challenging site to design, and the one requiring the highest level of precaution, is located on the mountain, one of the two sites in La Serena. This site is not only subject to unique climatic conditions—situated over 2,600 meters above sea level with lower oxygen levels and little humidity—but it is also difficult to access.
