With Matrix, the HRZ relies on a modern, privacy-conscious chat platform. In the newly established space “IT-Info & Austausch (powered by HRZ)”, IT administrators and IT security officers can find centralised information about incidents, planned changes, and new services. The platform also provides an area for informal communication and short questions to the HRZ.

The space is organized into several topic-specific rooms, such as

• [A] Info (HRZ) → central announcements and news
• [A] Zentrale IT-Störungsinfos (HRZ) → information on unplanned disruptions, service interruptions and outages
• [A] Updates und Upgrades (HRZ) → planned maintenance and system changes
• [A] Kurz gefragt / Info an das HRZ → channel for direct questions to the HRZ
• [A] Kaffeeküche (TUDa IT) → informal communication among IT admins

Note that room names are provided in German, as this reflects the primary language used within the platform.

The space also includes project- or topic-specific subspaces.

All individuals responsible for the operation of IT systems at TU Darmstadt who are listed in cisOS as an administrator, or IT security officer are automatically added to the space. It appears directly in the chat client and allows access to its individual rooms. Detailed instructions on setup and usage can be found in the guide Chat Communication with the HRZ via Matrix (opens in new tab) (German only).

The new communication option was already presented at the 19th AdminDay on 30.04.2025 and the presentation slides will be made available on our website shortly.

Save the date: The 20th AdminDay on 07.11.2025 offers IT admins an excellent opportunity to talk to the HRZ in person, ask questions and find out more about the Matrix Space and other IT topics.
