One of the two TUnet Core Routers will be renewed as scheduled as part of a technology upgrade.
The upgrade will take place on Tuesday 10 December 2019 in the maintenance window from 08:00 to 16:00 hours.
In the course of the exchange there may be campus-wide short interruptions in TUnet services such as Internet access for wired TUnet connections from workstations and servers, in Wlan and VPN as well as TUphone (VoIP telephony).
During maintenance work, the second TUnet Core Router in the Gusshaus takes over all functions in the TUnet backbone. TU.it Datacenter Services are not affected by the conversion.
After the conversion, TUnet Services will have a modern 100 Gigabit Ethernet core router at their disposal that offers sufficient performance and switch capacity for future requirements.
We are anxious to keep the interruptions as short as possible and thank you for your understanding.
If you suspect a problem after completing the maintenance work, please first check the network settings of your system or contact the IT contact person at your institute.
