Maintenance on TUnet Internet connection security systems

On Monday, May 2, 2022 changes will be made to security systems to the Internet.

Update 9:00 pm: The maintenance work took longer than planned, but it has been completed successfully. Thank you for your patience!

In a maintenance window between 5:00 p.m. and 7:00 p.m. a necessary adaptation of the firewall setup is carried out. As part of the work, the PoC FW hardware will be upgraded to the more powerful production hardware. This is a further step towards modernising and increasing the stability and performance of the TU Wien's internet connection.

This affects all wired TUnet network connections for end systems in offices, as well as server systems in server housing and data centre environments. During the specified period, there may be repeated interruptions to the internet connectivity to and from TUnet and its services.

We will endeavour to keep the interruptions as short as possible and thank you for your understanding.

No changes to your end systems are necessary. If you suspect a problem after completing the maintenance work carried out, please first check the network settings of your system or contact the IT contact person at your institute. Also check the TUnet status, opens an external URL in a new window and currently listed messages on Home. If problems persist, send an email to or contact us at 58801-42002.
