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.

On September 9, 2025, the root certificate for the RADIUS server of eduroam and RWTH-institutes will be changed to the new DFN Community Root CA 2022 as part of a regular security measure. 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.

After several years of intensive planning and implementation work, the network renewal at RWTH Aachen University is approaching an important milestone: Since its launch in 2018, the finish line for the end of 2026 is slowly coming into view.

The completion of the measures in the individual university buildings marks the transition from project to regular operation. The aim of the network renewal is to modernize the communication infrastructure, which is in some parts severely outdated, and to put it on a future-proof footing—technically, organizationally, and operationally.

Artificial intelligence (AI) is no longer a topic for the future – it has arrived in the centre of society and is changing the way we research, learn and work. As one of Europe’s leading technical universities, it is therefore crucial for RWTH Aachen University to actively engage with the potential and challenges of this technology.
As RWTH’s central IT facility, the IT Center plays a central role in this: it develops technical solutions, ensures a data protection-compliant infrastructure and creates new services that enable the use of AI in the university context.
And not just since yesterday: For some time now, the IT Center has been working intensively on making artificial intelligence usable for the entire university.
