Maintenance TUnet infrastructure firewall

A firewall system protecting TUnet infrastructure servers needs to be renewed to guarantee continuity of services.

Update 1:00 pm: The maintenance work was completed successfully at around 12:00 noon.

In the course of the technology upgrade, the entire firewall hardware will be replaced. Unfortunately, this is not possible without interruption.

During the maintenance window on Tuesday, February 16, 2021 between 10:00 a.m. and 5:00 p.m., there may be short interruptions in the DHCP and authentication service for WLAN and VPN clients (no login possible).
Services of the outgoing mail router will also be temporarily unavailable.

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 and currently listed messages on Home. If problems persist, send an email to, opens in new window or contact us at 58801 42002.
