To increase the operational safety and to protect the systems in the TUNET, the TU.it uses a firewall system at the interface to the Internet.
Due to manufacturer recommendations in the area of safety-relevant aspects, for the elimination of possible malfunctions and support for new system features, the firewall clusters for the TUNET Internet connection as well as for the external access in the WLAN / VPN area are being software-upgraded.
The update is scheduled for a maintenance window from 09:00 to 17:00 on Thursday, February 14, 2019.
The firewall systems are implemented redundantly. Normally, there should be no longer impairment of the services concerned Internet / WLAN / VPN. Short-term interruptions, which require the rebuilding of connections to the Internet, are possible.
We endeavor to keep the interruptions as short as possible and thank you for your understanding.
Up-to-date information on TUNET status can be viewed on the TUNET status page.
