Hm... interesting. It seems to coincide pretty well with the pageviews drop:

But that was explained to me as "we started filtering spiders better". So I don't think that would affect Alexa's numbers but maybe it's a bad coincidence that around the same time something else happened that dropped the numbers. And the convolution made us all miss it.
