In the weekend of 21 and 22 November the biannual major ICT maintenance will be carried out on the network. This means that during the whole weekend (from Saturday 00:00 to Sunday 24:00) we cannot guarantee the availability of all ICT services and facilities.
Our network has been built in such a way that all ICT systems and services in principal continue to function when one or more parts malfunction. During the weekend, however, we carry out maintenance on crucial parts of the network, which means there is a chance that ICT systems and services might be affected and fail. This is particularly the case on Saturdays. It goes without saying that we do everything in our power to keep these failures to a minimum.
Keep in mind that especially on Saturdays ICT systems and services and short or longer periods of time may fail. Think for example of
System administrators will use Sunday, 22 November to test systems following the maintenance work. It cannot be guaranteed that all systems will be operational again the whole day, but you can use them.
During the maintenance weekend necessary maintenance will be carried on the network. The maintenance work will improve the availability of the systems.
