# Maintenance Windows All maintenance work takes place between Monday 22:00 and Tuesday 02:00 (CET). There are exceptions, of course (e.g. an important security update). In detail, our maintenance window looks like this: - **Monday 22:00 to Tuesday 02:00 (CET)**: General maintenance window, here we also install Debian, Docker or GRAVITY updates - **Tuesday 01:00 to Tuesday 02:00 (CET)**: Automatic services (e.g. so that library updates take effect) and server (new kernel) restarts If you monitor your GRAVITY instance; the easiest way to set a maintenance window in your monitoring system is: every Monday 22:00 to Tuesday 02:00 (CET).
