Early access to Public beta 1.21.17.0 is out

What do they mean by “resources”? Is it servers or people? If it’s people, I get it because everyone is looking for help these days. But my fear is that they mean they don’t have enough servers to handle both MS and Steam beta, which tells me that it could be an overall lack of servers causing the problems we see on almost a daily basis.

If that’s not how this setup works, please feel free to enlighten me.
