Data centres are the largely unseen physical infrastructure that keeps many everyday digital services operating, from mobile apps and streaming to online shopping, cloud storage and artificial intelligence. Their expansion matters because AI requires substantially more computing power than routine online activity, driving a rapid push to build larger facilities.

– They process the data behind social media, email and banking apps.
– They store and deliver streaming video, music and online games with minimal buffering or lag.
– They provide the computing capacity used by AI chatbots, image generators and AI-powered search.
– They hold cloud-based photos, documents and device backups, often with duplicate copies for resilience.
– They enable search engines to return webpages, maps, images and videos within seconds.
– They support online retail through inventory systems, payments, recommendations and package tracking.
