Due to work on the storage system (Ceph Storage), the following applications may be affected during the maintenance period:
- RWTHonline: It may not be possible to upload or download documents in the “Sumission of Final Theses” application. File uploads should also be completed before the maintenance period begins at 8:00 a.m. to avoid errors.
- RWTHmoodle: Playing and editing existing videos and uploading new videos may not be possible. Only videos made available via the “Opencast” streaming application are affected.
- GitLab: Individual functions in GitLab may not work properly.
- Linux installation server: The provision of Linux RPM packages and Kickstart files may be affected during the maintenance period.

Due to a technical malfunction in the storage infrastructure (Ceph cluster), various IT services at RWTH are currently experiencing outages and restrictions.The relevant department has been informed and is working to resolve the issue.

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.
