This will also affect HedgeDoc (https://writemd.rz.tuhh.de/) and Mattermost (https://communicating.tuhh.de/), because the login of these services is provided by GitLab.
This is the first of several maintenance windows needed to bring GitLab up to the latest version. We will announce additional maintenance windows in the following weeks.
We apologize for this service interruption.
We also provide further information in the RZ newsfeed at https://www.tuhh.de/rzt/news.
If you have any questions, please contact our service desk via email address servicedesk+webdienste(at)tuhh(dot)de.
Kind regards
