Search Google by Data Centre / IP Address: querys SERPS by date centre ip

[mancunian]

Is it possible to query rankings on Google by a specific data centre and how would I find out the correct IP address to use to do this please.

Also can somebody please clarify in what order the data centres are updated and which data centre Google uses to serve my results when I search. Is it the one nearest my physical location e.g. Dublin or other?

I am keen to query the freshest results rather than wait for some slow propagation around the world.

Thanks in advance

Years ago there were websites that showed results from different datacenters. You could even see results from numerous data centers on the same screen. During a big google algorithmic update, many of us would watch the update propagate from datacenter to datacenter. There were a few specific datacenters that were usually the fastest to update.

But I don't recall the names of any of these websites. i vaguely remember that google eventually made some kind of change that prevented these types of sites from working, although I'm not sure about this.

It was cool, back in the day, to watch the Google batch updates roll out data centre by data centre. However, since a decade or so ago (Percolator/Caffeine) data centre updates have been incremental rather than batch, a continual process.

Subsequently Google has moved from front facing data centres to a global mesh network of thousands of edge nodes interconnecting with most ISPs; present in 1300+ cities in 200+ countries. Indeed renting rack space for Google’s ‘global cache’ has become a significant ISP revenue stream.

So when a search query is sent it may never go beyond one of those Google cache racks at your ISP... Data centres are now the deep back end rather than the interactive front face.

One can occasionally catch a glimpse of a query back to a data centre - instead of a near instant response time ticks by until a result finally renders; this is a query that the edge node can’t answer directly and, much as calling for a supervisor, a data centre answer is required.

Ah okay. Thank you for improving my understanding.

Yes I remember those old sites too!
