what does it mean when it says severs down and wont let you start the game?

Bought the division, but what is this separate thing.

I just bought this game but the servers seem to be offline. Is the game killed off by Ubisoft?

i mean - is this another game? It takes 40 gb of space - and wanted to know what is this before i download it i have the main game, why should i need to install this also? What this gives

Дорогие разработчики сегодня я купил игру вашу в итоге она не запускаеться хотя по параметрам мой ноут тянуть должен её спокойно.\
