Central IT provision only works with good communication and by exchanging information with local IT managers at the institutions – and this is exactly what the RWTH Admin Round Table is for.

On June 10, 2025, we successfully converted RWTH’s network connection to the German science network (X-WiN) to a new generation of routers. You can also read more information in the blog post. These important components of the network infrastructure were replaced with more powerful and energy-efficient devices. In this article, we take a look behind the scenes of the technical changeover: Why was it necessary? What was replaced? How did the complex conversion actually work?

In this series, the IT Center’s UX team reports on its work. When developing interactive systems such as websites and apps, not only HTML, CSS and JavaScript play a decisive role, but also usability and user experience. Put simply, this refers to the question of whether a system supports its users in achieving their goals effectively, efficiently and satisfactorily and what perceptions and reactions result from using a system.
At the IT Center, we also focus on the usability and user experience of our systems. User tests such as the annual satisfaction survey on the RWTHapp are a key tool that we use for this. You can find this year’s results here.

From this point on, only the new certificate will work – it will no longer be possible to use the old one. To ensure that you remain connected securely and without problems after September 9, you should update your WLAN configuration in good time.

We have already told you about RWTHgpt in our previous posts. Due to the success of RWTHgpt, RWTH Aachen University decided in the summer of 2024 to make the infrastructure used at RWTHgpt available to other universities throughout the state in the future. This led to the creation of the KI:connect.nrw project, funded by the Ministry of Culture and Science.
