I found a list of Google IP's that use the old methods and the updated BigDaddy infostructure. The changes in results for search terms is stagering and alarming. Compare your sites old a new placement and you'll see what I mean.

64.233.161.104 old
64.233.171.104 old
64.233.179.104 old
64.233.189.104 old
216.239.37.104 old
216.239.39.104 old
216.239.57.104 old
64.233.167.104 BigDaddy
66.102.7.104 BigDaddy
66.249.87.104 BigDaddy
66.102.9.104 BigDaddy
66.102.11.104 BigDaddy
72.14.207.104 BigDaddy
216.239.53.104 BigDaddy
216.239.59.104 BigDaddy
216.239.63.104 BigDaddy

Well I only did a limited test. I tried one of the old IPs and one of the Big Daddy IPs and tried 3 or 4 searches where I know one of my pages shows up on page 1 of the results. In all cases the page was in the exact same place in the results at both the old and Big Daddy IPs.

Not really a scientic study and hardly enough results for it to mean anything, but I seem to be doing the same for my limited test.

I see big difference on keywords - mostly on my secondary terms and phrases. moves downward of 10-15 positions.

I alkso noticed that some of the old IP's are now BigDaddy IP's. I read they are all being changed to BigDaddy (one about every 10 days).

I think that BigDaddy is being used 100% now.

By March 29th, Bigdaddy was fully deployed and the old system was turned off.
