This incident has been resolved. We have backfilled the missing data in our Reporting suite.
As for Win Logs, you should receive the missing impression data in your next batch with the correct timestamp; not in the "backfill/" directory as previously stated.
We apologize for any inconvenience.

Identified
As of 14:00 EDT on September 15th, impressions are underreported in batched win logs and the Reporting suite. We will backfill the data for the Reporting suite, and win logs will be backfilled to the "backfill/" directory in S3. A fix has already been identified and we will provide an update once completed.
Real-time Win Logs (both joined and unjoined) and Metamarkets Bids & Wins reporting are unaffected and will not require a backfill.
We apologize for any inconvenience.
