Update mare la rezultate in DC-urile Bigdaddy.

Ma numar si eu printre cei care au avut de castigat dupa ultimele miscari facute de google. Tin sa precizez totusi ca inaintea update-ului Jagger, cu doua zile, sa intamplat acelasi lucru. Sper ca de aceasta data, sa nu am surprize neplacute!

@WeaselMan Fii mai diplomat! Sa pastram un ton constructiv in aceasta sectiune a forumului.

Take a look:

BigDaddy is more than an update.

It's the adoption of a new "infrastructure" plus (probably) some changed software. While nobody will tell us what they mean by "infrastructure", my guess is that by "new infrastructure" they mean the migration of servers to their own version of Linux (Goobuntu). Another guess is that the new linux has some custom or otimized features that alow to do other things with the Google software (things like running their algos more deeply to better filter spam etc.)

Being something more radical than a simple upgrade, it will not spread as fast as usual to all the data centers.

The “BigDaddy infrastructure” has been running since the end of november on a single "test" data center; at the start of january they have started implementing it on "live" data centers. New data centers are being migrated at the rate of about 1o days each. Assuming a total of about 20 data centers, it will take a good part of the year to cover all of them.

How do Google datacenters work?

Usually, when you type www.example.com a DNS lookup takes place: the domain is searched, its corresponding IP address is found (eg. 123.123.123.123) and the request is sent to server 123.123.123.123, hosting www.example.com

When you type "www.google.com" something quite more complex happens. Depending on a few factors you are redirected to a different data center. The main factors are geographical location (you tend to be served the centers that are physically near) and load (if a data center is overloaded, you are switched to another center)

So, whenever you go to www.google.com you can see an "old" data center or a "BigDaddy" data center and its' not easy to tell them apart.

But IN THE AVERAGE, as your users are seeing a random mix of data centers, you should see a gradual introduction of the Bigdaddy effect. For example, we can assume that on jan 4th the first Bigdaddy center went live and so approximately 5% of the global Google traffic went through BigDaddy. When 10 data centers will be under BigDaddy, 50% of the traffic will be through BigDaddy.

So, if since the beginning of january you see a gradual trend in change (be it a good trend or a bad trend), that's probably the Bigdaddy effect, and (again my guess) expect it continue in the same direction for a few more months.

If on the other hand you see a sudden change on a specific day, that's probalby something different, the usual Adsense rollercoster.

A note: if you are in a non-US country, then (presumably) when the nearest data center will migrate that will generate a strong, sudden, variation. Also, bear in mind that BigDaddy doen not related to Adsense specifically, as far as we know. I only effects the Google searches, and all it can change is traffic. If traffic is the same but your earnings change don't blame BigDaddy!

Q: Is Bigdaddy still on track and launching?
A: Yes. Remember that Bigdaddy involves new infrastructure and is not just a data push or algorithm update. Don’t take it as a promise, but I’d expect a new data center to be converted to Bigdaddy roughly every 10 days or so. Again, take that as a rule of thumb. There are smart folks doing this transition, and they’re deciding how to do it in the best way.

In case you don’t want to download a 70 megabyte audio file, here’s the latest on Bigdaddy. Bigdaddy continues to roll out and is now available at three data centers. In addition to 66.249.93.104 and 64.233.179.104, Bigdaddy is now up at 216.239.51.104. We’ve been going through the spam feedback and acting on it, and reading through the general search feedback as well.

Q: Will those IP addresses always show Bigdaddy results?
A: No, not always. Sometimes data centers are taken out of the rotation for testing or other reasons.

Q: Is there an easy way to test if a datacenter is running Bigdaddy?
A: There’s not a definitive way outside of Google. But the [sf giants] example that I mentioned in my pre-Bigdaddy 302 post remains a pretty good test. If the query [sf giants] returns giants.mlb.com, the odds are pretty good that you’re hitting Bigdaddy.

Q: How will I see the switchover happen?
A: It will happen naturally as more data centers switch over to the Bigdaddy infrastructure. The more data centers there are using Bigdaddy, the odds of you hitting a Bigdaddy data center in the normal rotation go up.

Q: Can I still give spam or quality feedback?
A: Absolutely. Follow the same instructions from my original Bigdaddy post. I’ll ask someone to review any new spam feedback, and I’ll request that someone look through the non-spam search quality feedback looking for issues as well.
