As it happens, the matching servers used in the North American data centers were recently upgraded to higher-performance models. Continued optimization of this new equipment has allowed us, as of July 16, to increase the maximum number of simultaneous logins across the NA data centers by 18,000, or approximately 750 per World server.
A matching server upgrade for the EU data centers, while currently planned for the immediate future, however, is still pending. As such, until the upgrade is implemented, it will be difficult for us to raise World login caps to the same degree as those of North American Worlds. That said, the team is currently working hard to optimize existing servers in an attempt to increase the caps, if by a smaller amount, and will endeavor to make continued adjustments and improvements while maintaining game stability.
Despite the aforementioned cap increase, over the weekend of July 17 and 18, several North American World servers experienced periods of six to seven hours at maximum login capacity. As a result, character creation was unavailable for long periods of time, and players faced average login wait times of 10-20 minutes. For players residing on Worlds in the European data center, weekend login wait times were as high as 40 minutes. We deeply apologize for the situation in both regions.
