Identity Management (IdM)

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.
