But as soon as a project breaks ground, the question becomes: why here, and what for? On November 6 and 7, 2026, a European coalition is calling for protests under the banner "Stop Dirty Data Centres".

Imagine living in a building where all residents have to walk down the main street to visit their neighbors on the same floor. Absurd? Yet this is what many companies do with their data: they send it over the public internet to reach a partner hosted in the same room. A cross connect is simply the door between apartments, a direct, private, and ultra-fast connection between two pieces of equipment within a data center.

It is your legal responsibility, your GDPR compliance, and potentially your reputation at stake.
