E.G. is there a particular order in which they filter down or is it random?
What Im getting at is if you see your site doing good on say datacenter .in- is that better than say seeing your site doing good on .ex-?
Curious.
After having one of the most informative sites on our area place well for years it has disappeared this morning from www and the rest of the data centres..
This is a completely white hat site - now gone.
Where is the Google update thread as these changes are still going on. The serps are very different this morning as compared to yesterday.
His site had completly disappeared from NO 2 for him, even completly lossed for his company name :o
However looking from my machine, i see him right there where he was.
Looking at www1 www2 www3 though i see what he's seeing - not site.
Now www1 has completly disappeared for both of us - ie no google.
What the hell is going on?

Did I miss some/
Any additions or corrections?
Do they serve merely as backup / redundancy servers?
Do each run filters independent of the other datacenters E.G. are they working in conjunction with one another?
Do they have some sort of hierarchal structure? E.G. ex- is more important that in-?
Personally I could care less if there are 5,10, 100 for that matter if they don’t serve a distinct purpose independent of the next E.G. all working together as a team with specific goals/task to arrive at a final product.
Unless a process of operation is identified what is the benefit of running around checking all the servers? I suggest if you don’t understand the meaning of what your seeing when you view the results being displayed by the datacenters your wasting your time looking in the first place.

The www2 and www3 are not datacenters, the resolve in one of the real datacenters just like 'www.google.com'. And there is a also new one in Ireland: lm [webmasterworld.com]

...
Yes, but what are their responsibilities? Do they have some sort of hierarchal structure or is it totally random?
I will delete them (www2, www3) from my list. On several occasions, I have seen what you describe:
"data appeared on some DC, started spreading but never made it to all of them and then this new data was later gone on all DCs."
To me this begs the question, If the data was valid in the first place, does it represent a flaw in the system when it disappears? If the data was bad, why was it even posted anywhere? And finally, is there any pattern as to how far it spreads?
Has anyone else noticed any similar patterns or trends?
I realise it says dead in two of the data centers, but for one of my sites every datacenter reports as "Dead"
That has to be worrying doesn't it? I know there is alot happening at Google with the update, but this really spells trouble for my site, unless someone can tell me something that I don't know about this pagerank program.
which I think was mentioned further up the thread, I would love this dc to move over onto google, but somehow I doubt it.
P.S. - check-out plasma's good list of the recent DC's, including their IP addresses, here -

I can't bring up www-sj (main source for me to see US ads). Is it visible to others?
If this is to see your AdWords then do a search for the term you want on Google.com from your area. When the results come up ad &gl=us to the url and hit enter. You will then see the ads displayed in the US.
You can also change the US to UK, NL, DE, etc to see other countries.
