On 6/13/18, at 6:38 PM EDT, Search Tracker was discovered to be returning inaccurate data. The underlying location data and configuration was not affected, but the search tracker results were inaccurate. The analytics team began investigation, and deployed a fix at 10:23 PM EDT, scheduled to be applied by the overnight data sync job. The fix was applied successfully overnight and verified at 8:30 AM EDT the following morning.
An update to improve our data aggregation scripts had inadvertently introduced a bug that resulted in errors in the Search Tracker tables. Going forward, we will improve our testing infrastructure for data aggregation script improvements to catch such bugs.
