An ad serving issue yesterday, August 31st, from 4:30pm PDT to September 1st, 2am PDT caused less relevant ads or public service announcements (PSAs) to appear on some publisher pages. This was mostly limited to regions of Asia. Our engineers have now resolved the issue, and ad targeting has returned to normal. We apologize for the inconvenience, and are working to make sure that this doesn't happen again.
