e-Infrastructures are, by nature, invisible. It’s therefore difficult to understand the crucial role e-infrastructures play for research and education nationally, on a European level and globally. This talk will be a behind the scenes tour of GÉANT, Europe’s  indispensable e-infrastructure for research and education. The talk will show you our European and global network reach and capacities. It will explain how over the last 30 years, we have led the growing community of interconnected national research and education networks world-wide and have achieved a harmonious global service environment through global federations. The talk will also show why GÉANT matters to Europe’s digital leadership role and the role we play for research infrastructures, EuroHPC and the entire EOSC environment.
