I'm in the Midwestern part of the US, and so far, the Cloud DC is pretty smooth so far. Pretty much response times on interacting NPCs, items, interactable destinations has been quicker than it has been for the other NA DC, whether one place is empty or full of people. The Party and Solo instances have been pretty smooth and stable too. I feel like the latency from where I am may be a little lower than I'm used to.
