Description:

In order to ensure the greatest possible stability and availability of our Fortigate firewall and VPN, we will be carrying out scheduled maintenance work on Monday, December 29th, 2025 from 8:00 p.m. (CET). We will be installing security updates on the Fortigate routers in the Berlin BKI and BLU data centers.

Customer Impact during the Maintenance:

• No customer impact expected

Even if we do not expect any service interruptions during this period, there may still be brief VPN connection interruptions (up to 5 minutes).

The maintenance work affects both VPN tunnels that exist from outside into the SysEleven network and VPN tunnels between the cloud and the PVC platforms.
