seeing same thing here... the pattern was dead a week ago, 2 month high this last week, then dead again since yesterday. Also noticing that new pages made it into the index thur/fri almost instantly (like 10 minutes after creation), then were gone by the weekend, then back off and on... these guys are having major issues (intentional or not) with their datasets, folks. There's at least 2 very distinct results I get randomly (?) throughout the day... and they are NOTHING alike.
I don't think they will be any more storms. If by storm you mean, things as they were before March or May. We have a new Google and apparently everything is working just right to them, per Matt Cutts' statements. I'm also afraid that the adblock at the top of the organic results are there to stay.
She came back for us around 2AM PST on the 30th. Holding our breath to see what chaos this clearly BIG problem/issue/upgrade unleashes. To turn OFF gbot for the better part of a day for at least a good swath of the 'net is nothing to sneeze at.
This last with Gbot, have hit my site second time ... first time I have lose about 30 (15 000 unique visitors), this time I have again lose about 10 000 ... I now fear what will happen if Gbot stop again ...
I noticed at the end of June that GBot activity was down for one of my websites and has been for 2 weeks since. The website is 2 years old (.co.uk) and this is the longest that the activity has been low, 2 days is my longest before another spike by GBot occurs.
This website is only 260 pages and average pages downloaded per day is approx 160 as reported by WMT, That now is about 10 pages per day for 2 weeks continuous. Furthermore, pages have been reducing very slowly over the last 4-5 days, but I have read here that the site: operator is not very reliable these days? Over the last 5 days I have been losing 6 or 7 pages per day. Is this a result of lack of GBot activity to my inner pages?
I was hoping that this is a rare occurrence - then I came across this thread with a hint of optimism that things that are going wrong will soon be put right again.
I would like to add that my homepage consists of about 10 links (Coincidence?). My inner pages are 2 tiers deep but internal linking is not too bad so they should be found easily.
