Maintenance: central firewall, 11 May 2020, 8pm – 9pm

Message-Id: 202005091050
Time: Monday, 11 May 2020, 8pm - 9pm
Affected: All networks behind the central firewall (all GWDG services, all university institutes, WLAN)
Impact: None on schedule; possibly individual disconnections

Due to security gaps in the currently used firmware of the central GÖNET firewall, maintenance work must be carried out at short notice. We will change the system consisting of 2 devices in succession to another firmware version.

According to the manufacturer, our experience and the tests carried out, there should be *no failures*, since one device of the redundant pair will always be available.
