Affected: Entire GÖNET
Impact: One-time reset of all HTTP connections

Dear GÖNET participants,

Tomorrow, Thursday, we will be performing a security update of the central firewall.

This will require a switch between the two devices of the failover pair. Due to the high availability-functionality, this should have no effect on the network functionality. The only exceptions are
HTTP connections (retrieving web pages), which are reset once. All common browsers and tools should be able to handle this situation well; it should go unnoticed.
