Some thing wrong with adsence servers? Last few days I’m experiencing some troubles with logging. Some times says server not available

I think Google might be updating the AdSense servers along with the rest in this latest update. AdSense has been working fine for me the last few days though not too long ago I had some trouble logging in for a few minures.

A few weekends ago AdSense was down completely on my site and all sites I knew used AdSense including this forum. I found a few mentions of it on various forums on the web. The next day AdSense was back up though not displaying any useful ads and by Monday morning everything seemed to be working again.

Maybe there's still a few issues with the system during what I think is an upgrade of the AdSense servers.
