Since i'm not doing any major changes to my site the last two weeks regardless of these ups and downs... i feel that i'm monitoring whatever is happening with Google.
It started before sep 15th in my opinion, i have been seeing my BLs updated on and off every half a day or so from around the 12th. Before this, that test datacenter was the only one with this information. Now it's on Google, everywhere. The data is NOT presented the same though. It's similar but it's not the same, perhaps it's just filtered in a different way. The inbound links it shows are the same.
There was a major shakeup on Sept 15th in Google's SERPs. This was one of several that happened this summer. It is like one really massive rolling update with several phases. Thus far the major update dates for this summer have been June 27th, July 27th, Aug 17th and Sept 15th. Different sites have been hit by each update. One hallmark of all of these updates has been that when a site gets hit it totally disapears from the top of Google SERPs for all key phrases. On subsequent updates affected sites may see a partial or complete recovery.
My site for instance was not affected by the June 27th update, but it totally disappeared on the July 27th update. On the Aug 17th update it recovered for a few of its most core search phrases and then it completely recovered on Sept. 15th.
It is like Google is doing a major overhaul of its dataset one section at a time. The question is how much longer are these "rolling blackouts" going to take place?
