I'd like to pass along an update from Producer and Director Yoshida in regards to the instance issue.

I would like to inform you about the ongoing issues on the NA Aether and Primal data centers.

Due to high stress load and congestion, we are currently experience the following two issues:

  1. Congestion within certain instanced battle content
  2. Server crashes due to concentrated stress on the Duty Finder servers

Regarding the first issue, from around 8:00 a.m. (Pacific Time), we have strengthened the instanced worlds and diverted stress loads, enabling 20,000 players to enter instanced content each hour. As a result, the playable slots for instanced content have been increased significantly. We would like to offer our sincerest apologies that an extended amount of time was required to address these issues, as we strived to avoid large-scale server crashes within the data centers during our procedures. We will continue to monitor this situation 24 hours a day.

Regarding the second issue, we are experiencing continuous crashes within the Duty servers due to the consistently high stress loads caused by frequent matching requests from Worlds within the data centers. As we have confirmed that these crashes are causing some players to be unable to log in due to error 90006/90002, we continue to seek resolutions that address the root cause of these issues. As a temporary measure, we have implemented a work flow to restore the Worlds in 15 to 30 minute increments if the Duty server has crashed. We apologize for the inconvenience, but if you are experiencing the above error, we ask that you please try logging back in after 15 to 30 minutes.

We sincerely apologize for the large amount of time lost from your important early access time during the weekend. We will continue to monitor the high stress loads that the NA data centers are experiencing, and will continue to do our best so that players can play on all Worlds with stability. Once again, we apologize for the issues occurring for an extended amount of time.
