Maintenance work TUnet backbone Karlsplatz campus

The replacement of the Karlsplatz backbone router will take place during a maintenance window on Tuesday July 28, 2020 between 8:00 am and 4:00 pm. During this time all TUnet services in this campus area will be interrupted for up to 10 minutes.

Update 6:30 pm: The upgrade has been completed within the allotted maintenance window. We apologise for the approx. 15-minute unplanned Internet connection downtime between 10:00 and 10:30 am.

The TUnet campus enterprise network infrastructure is continually adapted to the needs of TU Wien. Currently, the implementation of a modern 100 Gigabit Ethernet infrastructure is underway to fulfil future requirements of the ever progressing digitalization process.

After the successful upgrade of the core routers and the Getreidemarkt backbone routers, this upgrade will be performed for the Karlsplatz campus. The replacement will take place during a maintenance window on Tuesday July 28, 2020 between 8:00 am and 4:00 pm. During this time, you will experience interruptions for up to 10 minutes of TUnet services such as Internet access via the wired network for servers and desktops, as well as WiFi and TUphone. This includes GUT access control systems and surveillance cameras. The communication between Karlsplatz desktops and the Karlsplatz server housing area in Freihaus will also be briefly interrupted. TU.it datacenter services are not affected.

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

After the upgrade is completed, the Campus Karlsplatz will be highly available, connected via four 100 gigabit links towards the TUnet Core and ready to fulfil future performance and switching capacity demands.

There is no need for config changes on your system. If you suspect a problem after our maintenance work has been completed, please check the network settings of your system or contact the IT contact person at your institute first.
