I am sorry Tedster. Yes you are right. But it all happened during 5 days as in a seuquence. As Gouri pointed out, they have yet to update their index. During last 8 months, sites have lost lots of indexed pages, lots of backlinks and google has even ignored many new things happening to most sites. So they need to catch up a lot. There may not be any algo change but results may change a lot when they put all these pieces together.
During last few months, webmaster have reported observations about google having data in different sets etc. We still have to see the complete picture which will come only after they complete this reindex.
The day we found webmaster account showing indexed pages as 0, is a start for this process and i consider this something important becuase this is just like a reset. And this is going to be a reset.
