Upon further investigation, the Cloud.gov team found that there was no gap in database log ingestion, and thus no incident.
While doing further querying to assess the impact of the apparent failed database log ingestion, a Cloud.gov engineer discovered that the query that was used to search for database logs was incorrect, which made it appear that database logs were missing and thus had failed to ingest. After fixing the query that is used to search for database logs, the engineer found that the database logs were ingested successfully with no gap from July 22 to August 26.
Database logs are continuing to ingest successfully now.
