“Dear Colleagues and Students,
We would like to inform you that we will be performing a software upgrade of our firewall management and logging systems to further improve the security and functionality of our network. Since only the management systems are affected, there should be no disruption to connectivity or ongoing data traffic. We have taken all necessary measures in advance to ensure the upgrade process goes as smoothly as possible and to avoid any interruptions.
The upgrade will take place during a maintenance window on Friday, June 26, 2026, from 11:00 a.m. to 4:00 p.m.
Our team will carefully monitor the upgrade process to ensure that network functions remain stable and available as expected during this time.
Please note that no changes can be made to firewall rules during this period.
Systems affected by the maintenance:
- Firewall management and logging systems
Your satisfaction is very important to us. If you have any questions or, contrary to expectations, encounter any issues after the upgrade, please contact us immediately at noc@tuwien.ac.at.
Thank you for your understanding and support as we work to continuously improve the security and functionality of our network.
Sincerely,
Network & Security Team
