Our contribution to sustainability in the digital world
We make decisions with energy efficiency and sustainability in mind - because what counts for us is not short-term profit, but the long-term, ecological impact of our actions.

OUR INNOVATIVE SERVERS
We are driven by efficiency. That's why we develop our own servers, which significantly reduce power consumption during operation thanks to customized technology. They form the basis for sustainable IT infrastructures without compromising on performance.
Function meets sustainability
We develop our servers in-house so we can optimize them for our applications and only include components that we actually need. We optimize airflow for efficient cooling.
The Circle of a Server’s Life at Hetzner
The life cycle of our servers starts with the development of our own models and assembly in our hardware department. If older server models are terminated after their use in the data center, they usually end up in our server exchange - tested, ready for use and affordable.
If the test reveals defects in the servers, they are repaired. If this is not possible, individual pieces of hardware are reused or recycled. In this way, we extend the service life of our servers to an average of eight years and save resources.
