I've been kicked off the server twice so far tonight and both times, it told me to check my connection. The first time it happened, I was able to reconnect again, but it was a little slow. The second time it happened, I was presented with an error message upon opening the launcher, telling me that it was unable to connect to the server and that I needed to check my connection.
Is the IP block in place again for North America or am I just having bad luck right now? Everything else is still connecting and running fine, and my connection hasn't actually dropped today (only for this game).
