Equinix opened its MD5 data center in Alcobendas, Madrid, with a €460 million ($534 million) investment, adding 4,400 square meters of colocation space to its existing Madrid campus. The facility, part of Equinix’s IBX network, features waterless cooling technology to support AI workloads without water consumption, aligning with sustainable infrastructure goals.
