This incident has been resolved.

We have successfully restored system. All functionality should be working as normal.

We are currently performing unscheduled maintenance on database to increase performance of notification endpoint. We expect less than 2 min interruption of services during the process.

Push notifications are back to normal operation. Notification tab is still slow to load.

We have temporarily disabled push notifications in order to stabilize system. This will result in delayed notifications and the notification tab is not working.

We have resolved the performance issue. We are still experiencing delays in our push notification service. We expect the service to return to normal operation within the next hour.

The issue was caused by a new experimental feature overloading the database. We are reverting the change now.

We are currently investigating the issue.
