Login via RWTH Single Sign-On (SSO) is currently disrupted. As a result, it is not possible to log in to any connected services.

There is currently a widespread disruption affecting, among other things, the SSO, though not limited to it. The root cause analysis is still underway.

Most of the services are currently up and running again. The analysis is ongoing. We cannot rule out the possibility of further outages.

Most of the services are up and running again. Please note, however, that the underlying issue has not yet been resolved, and disruptions may therefore continue to occur.

Explanation Following the Outage:
On June 22, 2026, starting at 9:00 a.m., there was a widespread outage affecting our services, which primarily impacted the RWTH Single Sign-On but was not limited to it. By around 12:00 p.m., the situation had largely stabilized, allowing users to log in via RWTH Single Sign-On again; however, other issues (e.g., with the IT Center ticket tool and RWTHmoodle) persisted. On the same day, between 4:30 p.m. and 5:00 p.m., the data center firewall was rebooted, which resolved the remaining issues. The disruption was caused by problems with the data center core switch. To ensure a lasting improvement in the situation, maintenance on the affected system was successfully carried out on June 30, 2026.

Due to maintenance work, you may experience connectivity issues when using Ritchy during the specified period.

We ask for your patience and understanding.

Due to the expired certificate for idm.rwth-aachen.de, no IdM applications and the applications that use RWTH Single Sign-On can be accessed.
We are working on a solution.
- An insecure connection message is displayed when calling up IdM applications.
- When calling up applications with access via RWTH Single Sign-On, a message about missing authorisations is displayed.

The certificate has been updated and the applications can be accessed again. Please delete the browser cache before accessing the pages again.
