An essential part of the safety measures at nine.ch is the constant adaptation to new circumstances. For the predictable maintenance work a weekly maintenance window is defined. This maintenance window takes place in the night from Monday to Tuesday between 0:00 am and 2:00 am Europe/Zurich.
During this period various maintenance work such as installing security updates will be performed.
Usually, maintenance work does not impact service availability. However, occasionally system reboots may become necessary and will be performed.
More comprehensive maintenance work will be announced at least one week in advance on our Status Page or by email.
