They did not do jack. My stats are still off as they were for the past week or so.
Now, the site that is 90% organic SEO traffic, 7% direct traffic and 3% referrals for the past 5 years suddenly shows 70% direct traffic, 30% organic SEO traffic and no referrals whatsoever.
The list goes on.
Google needs to hire people who really knows what they are doing. It appears that aside from mediocre programmers they have no quality assurance people on staff and rely on us to troubleshoot their work :)
