Well there are a couple details that come to answer this. The changes were applied only to part of the sites, and sometimes not to all sections. Did not have time yet to review and modify all of them. All that has been modified has been already restored in G's index. Everything that was not patched yet, is still down. You are btw right about the mid-dec change comeback (saw that too here and there) but i'm positive this isn't the case here.

Furthermore, is the exact timing. Google crawls our sites real often; more or less on a daily basis (this goes on like 3 weeks our of 4 each month). From the moment when the site was modified, it took precisely 2 days overall from the following google regular visit, for the spider to rescan our pages and then pages appeared in index back ok. The timing was too accurate in all cases following the page update moment (changes have been applied at diff dates to diff sites) to believe of anything else. We also have realtime Google spider monitoring, and watching it closely btw.


Good point, but I personally never stated all this as an absolute rule, but perhaps as a guideline which should be taken into debate. Obviously, it may apply different to different sites. Nobody can really say where the line in the sand is really drawn, but we may figure out that it exists. The fact that it didn't happen in your case doesn't necessarily mean its false. This appears to be an algo tuning, not a fixed limit; other factors usually do come into place as well deciding if a page is discarded or not. High PR sites for example appear to have less problems in several aspects including this one. We just had a too broad impact of this matter, and it has been noticed in several different sites making it very hard to be just a coincidence. That's why I decided to make this post.

So, if I would be a forum member here, and read this, and feel that it may affect me, I would simply try to avoid having more than 100 links from this point, or at least test if so, if I can do that. We have sharply lost thousands of dollars in revenues accros various sites these days due to this 'minor finetune' and it was menacing all our projected income from this line of activity for this year, so this was no joke for us. I do not intend to spawn yet another myth here cause we don't need that. Therefore, comments and other experiences are always welcomed.

Regarding page size, we don't have any pages nowhere close to the 100k limit, they are all less than 70kb with no exception.
