Lemmy Support

Hi there... I'm not sure if this is just because lemmy.ml is overloaded right now or what, but if I'm on a different instance and I want to subscribe to a community that lives on lemmy.ml, then when I hit the "subscribe" button, nothing happens. When I hit it again, it gives me this yellow "subscribe pending" button:

Is there a queue that the request goes into on the parent instance or something? Or do I just have to wait until traffic dies down to subscribe?
