AU is just having issues in general because of the datacenter. We are currently looking for another host, hang tight. To the other locations (US, EU, CA and AS), if you voted no, please give us details exactly what you were doing at the time of the NCP interference. This will only help us figure out the cause if it still affects you. It seems that it's less frequent but still an issue after reading the comments. Just note, ghosting is always an issue with vanilla MC and you can type in a command to fix that (/gf or /ghostfix when it happens to you).
