Bugs since P4Follow

I can't seem to find any information on this, but I'm curious as to whether the JP servers have been having the same problems as the NA/EU servers. Is it because of the location of the servers or is there just not enough support for the NA/EU servers? And if so, what can we expect on the 27th when there is even more server traffic? None of these bugs were present while I was playing in Phase 3 beta.
