Two forum threads, one at DigitalPoint Forums and the other at WebmasterWorld show how some, but not all, of the changes that took place on June 27th have been "fixed."

Just so you know, things aren't back exactly as they were. I know because I had some rankings show up in the June 27 update (which made me happy) and they are still there.

Traffic lost on June 27 appears to be bouncing back very nicely today. No changes made to the site since it got hit, just algo changes on G's end.
And some are reporting that the Google site command is beginning to work again.
