Monster Life reactions

I suppose it's like that. I notice it gets more laggy during the day, but a bit smoother and better during the night.

Does anyone know if monster life is one giant single server/channel or is it separate, since everyone from any world can access it and pretty much communicate with other players in different worlds?

It's probably one server, and not too "giant", either. They are assuming, probably correctly, that people will soon tire of Monster Life and it won't be as overloaded/laggy as it is now.
Of course, chicken-and-egg apply. People who might be interested enough to play a lot with it, will get disgusted with the lag and drop it.
FWIW, the IP of the one I get sent to (from MYCK) is 8.31.99.206, port 8587.
