Google has many data centers.Is there anyone which is always updated first or it is a random selection ?
No specific one that we are able to detect at this time. You might see some BigDaddy action first -- though.
Only google knows for sure... at 3-9 months usualy. The only patern seen is that the changing is made on weekends or holidays, when people are away from the computers as many as posible.
i like your blend of colours. the black text doesnt stand out on the red bg. your footer : "Praxis is proudly powered by zro.redtv and WordPress - Entries (RSS) and Comments (RSS). " is totally invisible to me...maybe its my monitor. cool site. keep coming.
Usually totally random. Whilst everybody will see the new updated search results, one region at a time. Because Google works magic with geo-location. So maybe let's say the 66.249.93.104 DC (Bigdaddy test DC in this case, but you could take any other example) get's updated first, and after that the results migrate to other DC's. Let's say that the first DC that the results migrate to, is 216.239.57.98. Now : 1. A guy searching from Canada, might see on www.google.com (or .ca , or whatever) the results from that DC. 2. A guy from Romania , might NOT see on www.google.com (or .ro , or whatever) the results from that DC. That's because Google uses geo-location tageting, and he display's results in your browser, from the nearest geographical DC, or the one that's least loaded with requests (if the first way fails somehow). So whilst everyone resides all over the world, there can't be any means of formulating an exact DC that update's first I think this clears your thoughts
