IT Center Ticketportal/Tickettool

Due to a widespread system-wide outage, the Webdesk (for agents) and the ticket portal (for customers) are currently unstable. Support via email, phone, etc., is still available.

Unfortunately, due to today's widespread outage, the ticketing system is currently unable to retrieve emails. This means that email support is also unavailable.

Partial outage has been resolved.

To resolve the current issues, maintenance work will be performed today between 4:30 p.m. and 5:30 p.m. During this time, there will be a service interruption affecting most of the services at RWTH for approximately 10 minutes. Please take this last-minute announcement into account when planning your work.

The work has been completed, and the issue has been successfully resolved.

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.

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.

Due to DNS disruption, the name servers of various providers are currently not returning an IP address for hosts under *.rwth-aachen.de.
As a workaround, you can store alternative DNS servers in your connection settings, e.g. the Level3-Nameserver (4.2.2.2 and 4.2.2.1) or Comodo (8.26.56.26 und 8.20.247.20). It may also be possible to reach the RWTH VPN server, in which case please use VPN.

Instructions for configuring an alternative DNS server under Windows can be found via the following links:

https:

You can also use VPN as an alternative. If you cannot reach the VPN server, you can adjust the host file under Windows according to the following instructions. This will allow you to reach the server vpn.rwth-aachen.de. To do this, the following entry must be added:
134.130.5.231 vpn.rwth-aachen.de

The hosts of RWTH Aachen University can now be reached again from outside the RWTH network.

Individual users may have experienced problems even after the fault was rectified on 25 August at 9 pm. On 26.8. at 9 a.m. all follow-up work was completed, so there should be no further problems.
