The affected floors are the 4th and 5th floor of the red Freihaus tower (DC).
During the restart, all devices on the affected floors will lose their network connections for approx. 10 to 15 minutes. This includes PCs, phones, access control systems and Wi-Fi connections. The restart should have no other noticeable effect.
