MW2 Beta server down or closed?

Right after i´d purchased the MW2 vault edition, my access to MW2 Beta disappeared.
Now I can´t even choose BETA from the “Game Version List” on

I’m 99% sure i’ve read that the Beta will be open until the stage of Early Access?
Or am I wrong? Thanks for y’all help!
Yours sincerely!

The MWII Beta ended today.

See for info.
