The maintenance windows are necessary to reach the current version 16. The way there requires successive updates of the system. The updates take several hours and take place in the background during the night. For this reason we recommend to avoid write accesses until the next morning. Normal use is possible in the period from 8:00am to 5:00pm. Please note that the version changes from day to day and functions and operation may change.
Details of specific versions can be found here.
This will also affect HedgeDoc (https://writemd.rz.tuhh.de/) and Mattermost (https://communicating.tuhh.de/) from 5:00pm to 6:00pm daily, as login for these services is handled through GitLab.
We apologize for this operational restriction.
If you have any questions, please contact our service desk via the email address email@example.com.
