For security reasons, the university IT department had to deactivate older TLS versions on the Exchange servers. To connect to the Exchange system, clients or systems must now support at least TLS 1.2. We do not expect any restrictions, as all current clients already support versions from TLS 1.2. If, contrary to expectations, you still encounter problems, please contact our IT support.


Use our speed test to find out whether the quality of your connection to the university network is sufficient for running various applications:


Tips for a quicker Internet connection on campus:

  • Do not use personal hot spots since they diminish the bandwidth and thus disrupt the entire network.
  • Turn off the wireless on your device, when you have taken your seat, and wait a moment. As soon as you turn the wireless on again, your device can connect to the nearest access point.

Planned maintenance work

In order to offer you fast and secure services, we regularly modernize our software and hardware. To this end, software and hardware developers provide updates, which we check and carry out swiftly, especially where critical vulnerabilities are involved. In addition, we renew, exchange and extend server and network components. Of course, we aim to keep disruptions due to maintenance work to a minimum. 

To make it easier for you to organize your work, you can find an overview of all our scheduled maintenance work below.
