Maintenance: Perimeter-firewall

Message-Id: 202202142111
Time: Thursday 17.2., 6 pm to 10 pm
Affected: network access at Uni, UMG, GWDG; WLAN at Uni-Campus; GWDG services
Impact: multiple disconnects of some connections

Two central network devices are being exchanged for more powerful ones, with the upcoming 100Gbit/s expansion of the backbone in mind. This was postponed two weeks ago due to an important scientific event. This may result in several short disconnects from/to the affected services or between the Internet and the campus network.
