In 2024, 11 data centers were located in or near Frankfurt, the most important German location, as well as in Berlin, Hamburg, Munich, Hanover, Augsburg, Mannheim, Heidelberg and Saarwellingen.
Admission is free, but the limited number of places must be booked in advance. Some data centers have high security requirements and therefore require registration with name and address as well as the presentation of an identity card.
