A thread at DigitalPoint Forums says;
"Well all 3 of my sites that got hit hard by the change on the 27th are now back where they are supposed to be and also other people reported that they are better now.
That was giving me a scare but I am glad its fixed."
Another thread says;
"I'm also seeing major improvements this morning. Google traffic is improved so far today and site command is back to normal. I hate to get to excited yet but it is great news. I hope all of you that were effected June 27th are also seeing improvements today."
