We are not quite sure the root cause, but tonight's battle arena seemed to cause some issues that we have not seen before that caused some serious slow downs within the game. Since it is close to 2am our local time, have been investigating for some time now and we are not any closer to figuring out the root cause we have made the decision to temporarily disable Battle Arena until we have a full team in the office tomorrow. We will provide updates as soon as we have them from the office later today. We apologize for this disturbance to the arena and will work our hardest to get it back online. ***Updates: 10:20 AM PDT - We've identified a root issue with our server configurations which had affected arena performance and are investigating a solution. We will be posting updates when we have additional information and progress on this situation. Once the issue is fixed we do plan on resuming the arena (time to be determined check back for details). Thank you for your patience. 1:30 PM PDT - We've resolved the performance issues with our servers and they should now be stable enough to support the continuation of the arena. We will resume the arena at 4:30 PM PDT.
