Welcome to WebmasterWorld Guest from 184.108.40.206
Yesterday I was noticing a lot of 'file not found' when displaying ads on my site.
Me too for the leaderboards meanwhile AdLinks were working perfectly!
I also noticed a lot of "Related Links" in my leaderboard. "Related links" have been on trial for the past month and only supposed to show about 1% or so of the time.
It was that bad yesterday plus my earnings were being hammered that I asked AdSense to take me off the trial...they haven't done it yet.
