I think I'm also seeing what Dusky is seeing with a few keywords, where the SERP yesterday returned to a state very much the same to what it was in early March (there was some kind of reshuffle around the middle/end of March, and again in early June). I started noticing it first on gl=uk, which then spread to all other locations except for the US, and then finally noticed it on the US as well. But today, I can't seem to find it anymore except on gl=se, which has always displayed SERPS closest (but not exactly the same) to the March one for this keyword.
As for the 301's, for the same keyword just a couple of days ago, I saw example.com ranked 3rd and then an alias of example.com (another domain name, 301'd to example.com) ranking 5th. I've never seen the alias being ranked before, so it was weird that Google seems to be not only ignoring the 301, but ranking it highly as well.
