NA/EU data center broken

After 2 days of early access gameplay I've noticed a strange discrepancy between NA/EU and Japanese datat ecenter, which I'd like to share with you:
NA/EU data center keeps spewing out all kinds of errors at us players and there are maintenances after maintenances trying to fix this or that.
On the other hand, I can log in to my JP server character any time I want and there are no problems with game play as far as I've noticed. I'm stuck with main character on EU server and can't move to JP center even if I wanted to :(

I would like to know why the NA/EU data center is all broken whilst JP center has no issues. Can't you provide the same level of service of NA/EU side of your customers, please?
