No further update and we continue to work with our vendor to resolve Sydney performance. Unless we have further information, next update will be at 5pm NZT.
We are aware of a performance issue with our Sydney shielding cluster causing platform instability. We are working with our vendor to resolve the issue.
We have moved affected customers to our backup clusters in Auckland and Melbourne. The issue has stabilised and our team continues to investigate Sydney performance problems and traffic will be reverted once we are confident the problem is resolved. We will provide further updates as more information comes to hand.
