Final Fantasy XIV will be resuming digital sales on January 25th. This information came in a very long update on the work planned to upgrade the games data centers and server capacity while announcing the opening of the new Oceania server in February.
The extensive update from director and producer Naoki Yoshida detailed the opening of the Oceania server on January 25th, with an opening of five new worlds from the start. For those within the region who want to transfer to these five new servers, the transfer fee will be waived. After this opening, the home World transfer service will be available to all players globally on January 26th. This gives them a day to test how things are going on the Oceania server.
With the new server and data center upgrades they will be rolling out, along with logins reduced to closer to normal levels as more players have progressed through Endwalker, this should make it possible to resume sales smoothly.
There's also an update on the expansion of the regional data centers. The Japanese data center will move to a configuration of eight worlds per data center and four data centers. This should increase login capacity over all the servers in Japan by 50,000. The North American data center will be getting a two-phase server expansion. Due to global supply chain issues the first phase will likely show up around August with the second in the first part of 2023. The first part is set to add four new servers and four more when the second part is completed.
The European data servers will get a similar expansion, beginning in July with the second half in summer 2023. The European servers will also get four new worlds in July and a new data center with eight new worlds with the second half of the upgrade.
The previously discussed data center travel system will also be planned for one of the 6.1 X patches. This will let players visit worlds in other data centers within the same physical data center as their own Home world. Cross-region visiting is technically possible but this is not something planned as of yet. But you'll be able to visit others within the data center offerings.
