Data Centers Becoming Independant?

google datacenters showing different results for same sites.

[internetheaven]

I have five sites, one of which has over 500 pages. 6 datacenters list 427 of them, 3 show 456 and the Google.co.uk shows only 106.

Anyone know why this is?

Different data centers almost always have different result sets (GoogleGuy mentioned something like that here at one point...)

Logic would say, they build the index at one data center, and then distribute it over the rest...and, since they spider what, 50-100 million urls a day with the 'fresh indexing' in place, that would be a pretty decent percentage of the db that would fluctuate, at any given time.

Hope that helps. :)

In the last couple of weeks, I have noticed a much larger difference between data centers than usual. But that might just be because I have a lot more pages indexed than I used to.

Mcavic,
I feel that too.

I use <snip> to check the datacenters.
When I search for my keywords, I find my site on varying positions on the first three pages. My site has nice positions in -ex and -sj. But when I search from www.google.com the results seem the come more from other datacenters than these.

I thought that at some point during the update, the results from these datacenters would be similar. But now with this 'continuous update'..... I don't know what is going on.

At this exact moment in time all data centers are the same. Do you think it will stick?

I'm thinking that the "rolling updates" may be about to start, I'm pretty sure GoogleGuy mentioned that all the datacenters needed to be aligned first.

They are not exactly the same, and haven't been for weeks.

If they were exactly the same, my index page would be visible in serps on other datacenters besides in and fi. :D

[annej]

You are right. It's the same in the top 10 in a lot of searches but there are exceptions.

It seems more uniform than yesterday tho.

I hope, as a user, that we will see some stability in SERPs. While the variable traffic is potentially good for my website, as a user I like stability. I used to bookmark Google SERPs -- really! I also like to move from computer to computer (home, work, school, library, friends, etc) and be able to find the same site (let's say one of those sites that doesn't have an easy url) by typing in a few keywords in Google.

Recently I've been getting totally different results for some searches from day to day, so that searching the same kw's the site I happily used yesterday is today nowhere to be found! This is really obnoxious -- are you listening GG?

This had better not turn into default behavior -- I'll have to start using one of my old freehost accounts as a bookmark file again. This is not my idea of convenience.

(my user POV says:)
-change no more than weekly
-move results up and down gradually

(my webmaster POV says:)
-all this tumult is great for me, because I get more variety in visitors

I'm not saying my webmaster half (heh heh) is my evil half or anything like that. But Google needs to have both happy users and happy webmasters and as a user, I'm started to get irritated . . .

I agree.

This Update is definitely different. Previously one data centre showed results and the changes would stay on that data centre. This time I see results on one data centre (completely different from others) and that result is seen in the other data centre seconds later. Hence results stabilize in proportions and not data centre specific.

Maybe I didn't get the concept of these data-centres but I think they are doing load balancing internally for the total no of servers they have :(
