Incident History

We experienced a technical issue that temporarily prevented some users from accessing features in the mobile app. The issue has been identified and a fix has been deployed. Everything is back to normal.

A routine health check to multiplayer nodes in Japan resulted in connection problems. The affacted server instance was recycled and upgraded. The user experience was not affected.

The service was down for a couple of minutes due to routine maintenance. All work has been completed.

Between Friday and Sunday, we experienced intermittent service disruptions caused by a data center–level infrastructure issue affecting network traffic distribution.

The issue impacted the managed load balancing layer responsible for routing requests to our servers. While the majority of requests were successfully processed, a portion failed intermittently. Because most traffic continued to function normally, the issue was not immediately detected by our alerting system.

After identifying the root cause, we replaced the affected load balancing components and web server instances as a precautionary measure. We also updated our monitoring and alerting policies to ensure that any request-level failures trigger immediate notifications, even if overall traffic levels remain high.

We are further reviewing system resilience to reduce sensitivity to partial network failures and are validating system data to ensure completeness.
