As a result of ongoing engineering work to increase ad yields, there was a temporary ad issue that affected users with articles on some of our sites for part of the day on 6/27 and 6/28. We are aware of the issue and things should be back to normal by Thursday the 29th. Thanks for your patience!
Essentially that's what happened which is fine if the net result ends up more positive but it's still a loss of earnings. I'm just glad it happened during a relative lull in traffic versus the Oct-Jan timeframe.
