Starting at midnight UTC Friday, June 12th, our internal instant traffic counts have not been updating properly. This has caused our instant count API to under-report, our ad pacing and cap detection to over-serve some ads, and our eCPM calculation to lag, impacting some auctions.
We have identified the root cause and corrected it, and we are currently replacing the missing data. This process is likely to require several hours. We will advise when all data is back in place and ad serving returns to normal.
