Access to several central systems will have to be blocked on 21 and 22 September 2023 for necessary work related to the implementation of the campus management system HISinOne (Apollo).

The lockdown affects all users of the above-mentioned systems:

In particular, the following functionalities are affected by the lockdown:

Examination registrations and de-registrations – should be completed before the system lockdown if possible, but can be sent by e-mail to the Examination Service during the lockdown if necessary.

The contact details can be found there:

Transcripts, certificates of good standing, study certificates and other certificates cannot be retrieved or issued by the Examination Service or the Registrar's Office.
