Affected: All networks behind the central firewall (all GWDG services and institutes)
Impact: scheduled none

Dear GÖNET-users, some maintenance work on the central firewall is pending:

Because of software-errors (problems with access by administrators) in the currently used firmware of the central GÖNET-firewall some short notice maintenance work needs to be done. We will change the firmware version of the system consisting of two devices consecutively.

According to manufacturer’s data, our experience and testing there should be *no outages* because one device of the redundant pair will always be available.
