I am not sure this even relevant to Google working on something, but in relation to our site some things are happening that look like Google is restoring some old backup data.
First of all, Webmaster Tools just started showing us HTML suggestions we fixed a few months ago. I know, because I have these exact pages in my old project "to do" log and now they are up again. Interestingly enough, we fixed these issues and the suggestions were gone for a few months. Now, the issues are still fixed (naturally, as we prefer not to do the same work twice), but HTML suggestions reappeared.
Second, when searching our site specifically using "site:" operator all our pages a out of order. We have a clear structure on our site and Google never fails to arrange our pages in intended order unless there are some ongoing adjustments on Google's end. Even if our pages are out of order they are very quickly sorted back and they were after the 24th, but now they are screwed up again.
