This seems to be a very special day. I don't remember if this ever happened to me, but this morning several Google services seem to be broken down for some reason. I'm unable to connect to Adsense or Adwords for about 1 1/2 hour now. The Google search engine and Google Analytics still work, so it's no general Google infrastructure break down.

Google stated to do maintenance on April 11th, but I wouldn't expect any timezone to have that date right now. Perhaps it has to do with Interest based ads. They should have been active since April 9th or so, but yesterday the ads obviously didn't change noticeably. Well, I'm keen to know what happens there right now and will post a note as soon as they tell us :) Just drop a comment if you've got a clue about it... TIA!
