IT Center Help - Dokumentation

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.

Die Wartung wurde erfolgreich beendet.

We will be making technical adjustments to the RWTHapp, IT Center Help, eduroam Device Manager, and Picture Manager applications during this period. There may be occasional minor disruptions while the work is carried out. We do not expect any major issues or outages. This measure serves to continuously improve and future-proof our services.

We will be updating our infrastructure for the RWTHapp, IT Center Help, eduroam Device Manager, and Picture Manager applications during this period. During this time, there may be occasional disruptions to these applications, but we do not expect any major problems or outages.

Maintenance has been completed.

No images are currently displayed on IT Center Help.
The cause has been identified and will be resolved shortly.

Pictures are being displayed now.

It is currently not possible to access the Status Message Portal via the "Current status messages" section on the IT Center Help homepage. Current messages are not displayed.
We are working on a solution to the problem.

Im angegeben Zeitraum wird IT Center nur teilweise zur Verfügung stehen. Das unterliegende Quellsystem wird aktualisiert.

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.

Der Uplink nach Frankfurt wurde erfolgreich auf das neue System geschwenkt.

Umbau des Uplinks nach Hannover beginnt.

Uplink nach Hannover auf das neue System umgezogen.

BGP v4/v6 nach Frankfurt und Hannover sind nun über die neue Routern funktional.

Es stehen noch ein paar kleinere Nacharbeiten an.

Wartung ist abgeschlossen. Der Datenverkehr läuft nun vollständig über die neuen Router!

Problematik mit der Anbindung zur Physik identifiziert, Lösung erfolgt morgen früh.

The functionality of IT Center Help is currently limited. We are working on a solution.

There may currently be problems with the display of content and navigation on IT Center Help. A solution is being worked on.

The issue has been fixed.

Due to an update between 2 and 4 pm, there will be limitations in the search and navigation on IT Center Help.
You will reach the manuals via direct links during this time.

Maintenance is extended until 4.30 pm.

The following functions on the IT Center Help home page cannot be used at the moment:
- Navigation and search do not work.
- Frequently searched pages are not displayed.
Direct links to instructions still work.
We are working on a solution.

Due to problems with the load balancers (F5), the majority of services such as RWTHmoodle, RWTH Single Sign-On, RWTH E-Mail etc. and all services behind the RWTH Single Sign-On are disrupted.

A technician from the manufacturer has now also been called in to solve the problem.

The fault has been rectified. However, there may still be delays in delivery or receipt.

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:

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.
