Country attribution skewed toward US for 2021-08-30 through 2021-09-03

[Jeff Klukas]

Data users - We have identified an error with geo attribution in the telemetry pipeline that has caused some fraction of pings to be incorrectly attributed to a location in the US. The pipeline has been reverted to a known good state, so newly ingested data will have correct geo metadata.

For the time being, analysis results segmented by country will be heavily skewed toward the US, especially for Sept 1, 2, and 3.

Early next week, we will backfill data for the 5 affected days and rerun ETL to correctly populate derived tables.

This incident is now resolved.

We completed backfills of historical ping tables and derived tables late last week, so analyses should now show correct geo metadata throughout the affected dates.
