There have been plenty of signs of updates over October with the Google algorithm. The last time we reported these shifts were on October 8th but I am seeing shifts reported on October 14th and 15th as well as the past couple days, October 17th through today.
Here is my traffic chart, showing a 15% lift in my organic Google traffic since Thursday, October 15th.
There is a huge WebmasterWorld thread with tons of chatter about what they are calling ZOMBIE Google traffic or the ZOMBIE update. The chatter is significant.
Here is a tweet showing a significant change on October 14th as well:

The automated tools show changes as well. Mozcast shows a spike on October 17th, SERP Metrics shows a spike as of yesterday, so does Algoroo and a new one named Accuranker also does. Both SERPs and advancedwebranking.com are pretty stable.
Did you notice updates this past week or so?
I suspect it is a bunch of changes, both Panda continued roll out, maybe this ZOMBIE thing which has no confirmation from Google or something else.
