As many of you have probably already been aware, Google has had a test datacenter in the works. For the most part people seem to like the results of this new datacenter. It is looking like this new datacenter will be eventually taking over and going live across all of Google. As Matt Cutts has stated here:http://www.mattcutts.com/blog/It will become the default source of web results in the next one to two months.I believe there is some different data and algorithmic changes, but according to Matt Cutts the primary change with this update is new infrastructure.Matt Cutts wrote:I see quite different results between the two, the latter being a lot more preferable personally. What happened to the datacentre http://64.233.179.99/ . Couple of weeks ago it gave me awesome rankings, now they dropped off a little. They tinker too much at google i think...Yeah for me the first IP address I gave (64.233.179.104) is going back and forth between old and new results. The two datacenters I quoted were the ones Matt Cutts gave. Maybe there is some kind of transition still taking place there.My site keeps fluctuating between old PR and current PR. I decided to try to quit looking until they get things on even keel.The pagerank fluctuation you are seeing has nothing to do with the Bigdaddy update though, I am sure you are just seeing an old datacenter from time to time that shows the older pagerank from a few months back.Matt Cutts made another post with regards to that one IP address not working. It explains why only one is returning the Bigdaddy results:Matt Cutts wrote:This smells me like an easy rant trying of Matts via speculations for his Google blog.I could not find anything extraordinary on this, Google always has the test datacenters. Even the datacenter that Dhaval found here http://www.ozzu.com/other-google-information-and-resources/big-big-big-update-fast-look-this-t55869.html was much more important than this datacenter, Matts named as bigdaddy .Absolutely not a big deal.You will see this datacenter also will be switched to another IP shortly.I am not sure I am following you Dolay. I think these new datacenters have some nice changes.Why do you think Matt Cutts is ranting? He is simply letting us know what is going on behind the scenes right now.Also that link you provided:http://www.ozzu.com/other-google-information-and-resources/big-big-big-update-fast-look-this-t55869.htmlThat is the same update as this. They have just made it clear that this update will be coming live into Google in the next few months and they have given it an official name now.It is almost 3 months since last PR Updated and as you stated on that Dhaval's thread. We even noticed and discuss the new unique algo on Google test datacenters. A usual PR+BL update with new algo is going to appear within these days. Arent we expecting before Matts news ?So why are we talking regarding this expected update like it was a Matt's foresights?My point is because of that otherwise like I said at Dhaval's thread this seems like one of the biggest ALGO change of Google which is more stricter to eliminate the pages filled with unuseful contents [autocreated links farm pages and the pages built by hijacked metas of ranking sites] I believe it is too early to speculate on that because Google is switching the IPs too frequently and there is not a specific IP that could be named as a test datacenter nor bigdaddy.Long stroy short: This become news at Ozzu much more earlier than Matts blog and no need to give any prim to his naming tryings for this update tough he made a big fault by trying to name an IP instead trying to name " the new ALGO" we are experiencing on some IPs which are not stable with same ALGOs.What we talked about in the other thread at Ozzu was more speculation than anything. Yes we all saw the other datacenters and the new results and thought there was possibly some kind of update coming in the future. Nobody knew for sure.The reason I created a new thread on this is because Matt Cutts, an employee of Google, confirmed that this update will indeed eventually be pushed forward. It is not a thread about discovery of this datacenter, its a thread which confirms what we all speculated will be coming true.This update has nothing to do with PageRank or Backlinks, but more to do with the results (SERPs) that you see on Google due to the new infrastructure Google is implementing and the confirmation that it will be going live in the next couple of months.Since the last 24 hours we have experienced higher googlebot activities and now I am seeing very unstable SERPs .Can anyone confirm if the SERPs on 66.249.93.104 are stable?If you compare with 64.233.179.104 they are totally different now and I hope the 66.249.93.104 will stable at main datacenters too.Any Idea about the current situation?64.233.179.104 has the results of the old datacenters at this moment.66.249.93.104 has the results of the Bigdaddy Datacenter update and I really like the results there.The bigdaddy update probably won't be pushed to the main datacenters until at least a month or more. It is still undergoing testing according to Matt Cutts.The ranking sites falling on main datacenters are ranking better on 66.249.93.104 .Since yesterday we lost several keywords ranks totally [interesting 3-10th position s are now not even within 1k] on the main datacenters but their rank better than ever on 66.249.93.104 .I wish Matts prediction will really be appeared this time
