Lumen identified that real growth is in 'east-west' data traffic—data moving between clouds and data centers—not the commoditized 'north-south' traffic from a user to the cloud. Acquiring Alkira accelerated its ability to serve this high-growth, complex market, creating a key strategic differentiator.

AWS's partnership with Rio Tinto funds a new refining method for low-grade copper. While the initial volume is small, success could make 70% of previously uneconomical ore viable, tripling supply and lowering prices for future data center build-outs.
