August 11 is a deadbolt - Lowest eCPM, twice in a row

[Rodeo]

Today on Aug 11 (only 3 hours left to shut down 11th), I'm seeing the lowest eCPM that I can remember so far. Incidentally, August 11 in 2009 was exactly the same, eCPM being nearly half of August average.
Any history to Aug 11?

Senior members who can chalk out reports for Aug 11 in 2008 and before, since I do not have them before June 2009 in this new account.

today, first semi normal day in weeks, in fact after the whole july and part of june. Not quite the same but almost a normal day for me, as for the rest of days... this month is low even as in past years was one of the highest.

I keep record of my stats, june may begins to raise, june is one of the highest, july follows and august keeps the trend or begings to fall, but this year everythin is upside down since the end of may
