Tim Mayer reported the Fourth Weather Report at the Yahoo! Search Blog.
We will be making changes to the ranking of our index tonight. I would expect that this update will be mild and quick compared to recent ones but will impact the ranking of some sites.
If you have any feedback for us about the new index please email: firstname.lastname@example.org.
We look forward to hearing from you.
