< continued from: [webmasterworld.com...] >

Stop looking at [64.233.187.104...] aka [gfe-jc.google.com...] when you should be looking at [gfe-eh.google.com...] aka [72.14.207.104...] instead...

On the latter DC there is a big cleanup of older Supplemental Results in progress.

Oh man.. I had to go 4 pages back to find this thread :-)

Just to say there is some movement on the Mother of The New Infrastructure 72.14.207.104

Please check your testing key-words / key-phrases and tell us whether you see any changes.

Thanks!

There are some completely unrelated results for a site:domain.com search. Not seeing much else.

Oooh. A site that almost disappeared because of non-unique page content, non-unique title tags, meta descriptions, etc, just a few months back (only 8 out of 30 pages remained indexed, 6 of those as supplemental), fixed the problems and got re-listed a few weeks later.

Suddenly, now, all but just one internal page are completely gone. Index page gone too. Hmmmmm. Not my site.

All other things I watch are fine.

.

Oh, I see what the problem is. The gfe-eh DC, which updated Supplemental Results about a month ago, has reverted back to an older index, the same as the index that has been showing on gfe-gv for several months before. The Supplemental update at gfe-eh has been reverted back to how it was back 3 or 4 months ago.

What is probably happening is that gfe-eh is offline while something is being changed, and so all calls to that DC are routed to some other DC for the moment. Maybe the real change will be seen in a few days time. At the moment we are just looking at the curtains, and can't yet see the man behind.

I think something is happening on most of the rest DCs too. Maybe not big change, but change for sure. For example, I see a site being deindexed. Of course it could be a "revert back" as g1smd mentioned.

It's spread to 66.102.7.104

I think it's a reversion. Can't wait to see what Google trots out in the near future.

This seems to be the new way of things:

For a short while, and maybe several times in short succession over a period of days, Google reverts to much older data (presumably by temporarily routing queries to some other datacentres) while the "real index" is taken offline and updated in some way.

Not all datacentres are done at the same time, but within a week or so, ever newer data begins to show up on most of them.

I think this may have been happening for, perhaps, almost a year now.

Man .. the serps are bad ... we're even being beaten out on one of our keywords by a website who's description being shown is an ASP error code. What the heck is up with that?!? And the others are directories of spam.

I've seen this happen much moire frequently and in much less time frame. For exmaple my homepage was cachced on the 18th yet today the index has reverted back to saying it was cached on the 12th. I've watched a couple times where they index new content for several days then revert back to data from 7-10 days ago. This usally last 1-2 days until they start indexing new content again.

Hmmm..on checking 72.14.207.104 I just noticed a site I managed has moved from #8 or 9 to #6 or #7 for "widget" and moved from #12 to #8 for "widgets", which was a critical movement for this site.
Haven't really checked across the board so don't know yet if other dc's are doing this.
Thanks for the heads up reseller!

i like the look of 72.14.207.104

do you still think this will spread, MC indicated things will settle towards the end of this month, so maybe we'll be seeing movement soon.

From Matt's blog:
In essence, if a page hasnít changed since the last time we fetched it, thereís no need to fetch it again.

What I dont understand is how would google bot know if the file had changed or not until it had been fetched? .. or am I just missing something here.

Yes .. but what if it is a dynamic page.. the actual file date wouldn't change.. only the content.

Most servers, by default, do not serve a last-modified header with dynamic extentions, so the page will always appear "fresh" to a user-agent. In PHP (and most languages) last-modified headers can be dynamically generated for each request (or page).

Yes my server does not pass that information to the browser, but should we be? I don't mean an across the board freshness date of "now" but for say .. product pages .. give the browser the last modified of the item?

Good evening Folks,

I see more changes (or changes continue) on 72.14.207.---

Wouldn't call big changes. One can say its a kind of White Revolution.

Something like;

The King is Dead. Long Live The Queen! :-)

That might mean a Supplemental Update is in progress.

That sort of update sees Supplemental Results that represent URLs that have been redirected, or have been 404, for the last year getting deleted from the SERPs at long last.

It also sees new Supplemental Results being created for any URLs that have recently been turned into redirects, or have recently gone 404.

Those new Supplemental Results will now hang around for a year before being deleted. They are there to help people who looked at your site before you made those recent changes and who now what to see that information again.

Finally, a Supplemental Update sees new Supplemental Results being created for URLs that still return a "200 OK" when accessed, but these are for pages that have recently been edited.

If you search for current content associated with that URL then it will show as a normal result. If you search for stuff that was previously at that URL but which was removed from the page some time in the last few months then that same URL will rank, but this time it will be shown as a Supplemental Result.

The only Supplemental Results that you need to woory about, the only ones that you can actually "fix", are those that still return a "200 OK" and which represent live Duplicate Content. That Duplicate Content may take many forms including: www vs. non-www, multiple domains, differing URL parameters for the same content, http vs. https, URL CaPiTaLiSaTiOn {IIS only!}, "index" vs. "/", as well as the unique title/meta description problem, and so on.

There was a Supplemental Update a few weeks ago at gfe-eh and a few other datacentres. That was briefly reverted a few days ago. It was re-applied today. maybe it is now spreading to other datacentres, for wider visibility? (I haven't checked). The Supplemental update has not been seen at gfe-gv at all, yet.

What about the edited pages that don't go supplemental? I have lots of those. And supplemental pages that have been edited, too.

Ah, I see. Well I think that 72.14.207.99, and 72.14.207.104, and 72.14.207.147, etc, all count as one: 72.14.207.*

A small number of nearly-two-year-old Supplemental Results, results that were cleaned up a year ago, are back!

I have no idea why.

These are Supplemental Results returned for a search query for a word that is no longer on the page, and has not been there for nearly two years.

I need to check my records. It might be only 18 months. :-(

hi... new to Google Search News...

Checking my rank, I noticed that on one datacenter (216.239.51.104) I don't rank at all whereas all other datacenters rank me at #7.

Upon checking the location of this datacenter, most websites state that it's supposed to be non-active.

Is this correct? If it is, then why am I seeing this datacenter? The serps are totally rubbish ont this datacenter by the way.
