On Wednesday 9 July at 14:00 the Department of Computer Science GitLab system will be taken offline for maintenance and upgrades to the GitLab software and OS. Work on the system will start at 14:00 and may take until 18:00, although we will attempt to minimise the time that GitLab is unavailable. This notice will be removed when the work on the server is completed and tests indicate GitLab is operating normally.
