Question before spending months/years on Nostalrius

Heya guys.
I'm an old school WoW player and I want to feel and experience WoW how it was back in the days. Now I have a question before I start playing here, I don't know if the devs made contact with Blizzard and if Blizzard is aware of this private server, but is there a chance that we know it won't shut down for the next few years? What happened to me is I've spent a whole year of playing on a popular private WoW server and it got shut down which left me with absolutely nothing. I understand it's a private server and I'm taking my time and chances but I just wanted to know if it's 'safe' (if you know what I mean). Hope I didn't cause any trouble.
Thanks and see you ingame. =3
