On 20 September, you can expect several brief interruptions between 6:00 PM and 11:00 PM, each lasting up to a minute. During these interruptions, you will not be able to use Radboud University's central ICT systems, including email, Wi-Fi, BASS, OSIRIS, and Brightspace.
Although you may not notice the interruptions, it is still advisable to assume that ICT services will be unavailable that evening. This will help prevent sudden disconnections before your changes are saved.
