Testing Environement 20th to 27th

Is the new community testing environement that was announced in Community Update #2 already online?

Thank you, I enjoy it so far. The new map looks great and is very rich in variety. The new hardcore coop is addictive as hell. BUT there is one huge problem. I can't use my own key binds because the default keybinds can't be changed. If you do change them, i.e. C for crouching then you will push C and you will crouch AND the comm menu will come up. This is heavily annoying and it doesn't allow for tactical gameplay at all.
[Several other players seem to have the same problem!]
