Maintenance Windows. Maintenance windows shall be agreed for periodic, scheduled or unscheduled maintenance work on the systems of Host Europe GmbH and its suppliers, which are necessary to uphold and secure the ongoing operation and to carry out updates or upgrades. Any limitations to the availability through such necessary work shall not be defined as downtimes. As a rule, system maintenance is carried out on weekends between Saturday 12:00 and Sunday 12:00 or at night on any weekday in the time between 23:00 and 09:00 on the following morning. In exceptional cases, system maintenance may be carried out at any other times with due consideration for the lowest possible limitation of ongoing operations. Host Europe GmbH will inform the customer of scheduled system maintenance as early as possible.
