Authentifizierung (RWTH Single Sign-On, MFA)

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).

Due to the replacement of central switches in the data center at the Seffenter Weg and Wendlingweg locations, there may be brief outages of the services operated in the data center between 4 p.m. and 7 p.m., or 10 p.m. at the latest.

As a result, authentication for Wi-Fi and VPN will also be temporarily unavailable, meaning that logging into Wi-Fi (eduroam, RWTH institutes, RWTH devices) and all VPN areas may be temporarily disrupted.

The maintenance will also affect various IT Center services, which may also experience brief outages. This message has been extended to the affected services.

During this period, the routing of the previous XWiN routers (Nexus 7700) will be switched to the new XWiN routers (Catalyst 9600). These routers are essential for RWTH's network connection. This changeover also requires the migration of the DFN connection, which is switched redundantly to Frankfurt and Hannover, and the RWTH firewall to the new systems.
There will be complete or partial outages of the external connection during the maintenance window. All RWTH services (e.g. VPN, email, RWTHonline, RWTHmoodle) will not be available during this period. The accessibility of services within the RWTH network will be temporarily unavailable due to limited DNS functionality.
