For the past week or so, I've been seeing a lot of chatter around a Google updating happening. The thing is, it is hard to tell what is going on right now.

The kicker is on Friday, Matt Cutts tweeted that there is an update being pushed out over multiple weeks. Matt said:
Multi-week rollout going on now, from next week all all the way to the week after July 4th.
I think this is in response to spam algorithm and not the softer Panda algorithm - although, they both might be updating now, as well as other things might be going on at the same time.
The reason I think it is spam algorithm related is because @screamingfrog tweet about a [car insurance] query was what Matt responded to.
I will see if I can get more details from Matt Cutts and will let you know the details when I hear back.
