Do I need to move?

I have been out of the swing of wow for quite some time. I plan to main a warrior, alliance side for shadowlands. I was concerned to see that this server now looks like its dead? I am not sure if I need to roll back to horde on a different server. I dont want to play a dead server come shadowlands. =S Advice?

That side of the server is dead. This side of the server is fine.
