I’ve had emails from 4 different YPN publishers who tell me that the ads on their blogs are not showing and have not been for most of the day just gone by. Forums like Digital Point’s YPN down? thread seem to confirm that the problem is more widely spread than just a few isolated cases.
I just logged into b5media’s YPN account and the back end is not working but the blogs we’re running the ads on are definitely not showing them either.
I guess publishers need to remember that YPN is in beta and from time to time will have problems. It’s not really any comfort but part of the process.
update: not long after posting this I started seeing ads on our blogs that run YPN so perhaps things are back up and running again.
