Bidstream truncation
High-volume bidstream feeds often truncate or sample records under load, and truncated records can silently drop the geo field entirely or truncate coordinate precision, biasing which impressions are geo-resolvable.

01
Detection
Rate of missing/null geo fields spikes correlated with feed volume/load, or coordinate precision degrades under peak QPS versus off-peak.
02
Mitigation
01
Monitor geo-field completeness rate as a function of feed volume and alert on drops
02
Treat volume-correlated geo-completeness dips as a truncation signal, not random missingness, when weighting geo-based aggregates
