The Resolution for this Issue
We are now ready to deploy the backup development servers to the public lobby servers, which will improve the capacity management of the lobby server and raise the maximum number of players in the queue to around 21,000. Since this will not require any maintenance, we will err on the side of caution and proceed with the deployment outside of peak hours. It is scheduled to be completed late in the night of December 7, Japan time.
They didn't add new servers they increased the cap of how many people can sit in the login queue before 2002 happens.
