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: www.ionos.de/digitalguide/server/konfiguration/windows-11-dns-aendern/ https: www.netzwelt.de/galerie/25894-dns-einstellungen-windows-10-11-aendern.html 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 https: www.windows-faq.de/2022/10/04/windows-11-hosts-datei-bearbeiten/

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.
