UPDATE - April 6, 2011: Incorrect historical data has been reprocessed and all metrics should now be correct. This issue is now completely resolved.

UPDATE - March 22, 2011: Our engineers have diagnosed the issue and a fix has been deployed. All data coming in after March 22nd will have correct demographic data associated with it. However, historical data still needs to be reprocessed - this will be performed some time this week. This means by next week everything should be back to normal.

Dear Kontagent Users,

We've recently discovered an issue where incorrect DAU numbers are being displayed when filtering for certain demographics. Our engineering team is already working on resolving it and everything should be back to normal after the weekend.

This thread will be updated as more information becomes available.
