few moments ago i found this article in a big german online magazine for players (www.pcgames.de):

Rainbow Six Siege: Am Wochenende kostenlos spielen

Wenn ihr schon immer mal einen genaueren Blick auf Rainbow Six: Siege werfen wolltet, dürft ihr euch an diesem Wochenende nichts mehr vornehmen. Der Publisher Ubisoft veranstaltet nämlich vom 16. bis zum 19. November 2017 ein weiteres Kostenlos-Event, bei dem ihr ganz unverbindlich einen genaueren Blick auf den Taktik-Shooter werfen könnt.

At the buttom of the article you also can find a link to the official twitter account of Rainbow Six Siege announcing the free weekend (in english): Rainbow Six Siege on Twitter
