WirelessLAN (eduroam, RWTH-guests)

We have received preliminary information about upcoming security updates that we will need to install on a number of network components of the RWTH network.

Generally, installation of software updates is a routine procedure that we perform quite regularly in order to ensure continued secure operation and management of our network. This time around, we don't have detailed information about when exactly updated software will be available to us, which obviously makes planning a bit more difficult. It may be necessary to install updates and reboot network components on short notice, which may cause short but potentially noticeable service interruptions. We try as much as possible to do this outside of regular usage hours.

We will provide specifics about what systems will be concerned once we actually have this information ourselves.

In the course of a software update, the individual proxies are restarted. Due to the HA implementation, there should be no failures. Affected are among others mail, WLAN VPN/Shibboleth (because of LDAP).

During the specified maintenance window, the IT Center will perform maintenance on the MySQL databases used by the Multi-Factor Authentication (MFA) service. As part of the maintenance, the databases will be unavailable for a total of approximately 15 minutes.

During this time, new logins to services using RWTH Single Sign-On will not be possible. Existing sessions will remain active and will not be affected by the maintenance.
