   Impact from this issue has concluded. For a period of time (different between US and EU instances, noted below), queries spanning data older than the most recent 2 hours with certain GROUP / WHERE clauses returned inconsistent results. Data was never lost, and reruns of the same queries will show the previously missing data. US impact times: 21:50 UTC - 23:20 UTC EU impact times: 20:50 UTC - 23:20 UTC
