In reference to the reports of sites being hit on Oct 4-5th...

We have seen a few sites drop in G* referrals on 4-5th as well, however rankings seem fairly static in serps, at most 1-2 position drops, that are done by some kind of customization (even when tracking settings and cookies are blocked)

To me, this Oct 4-5th change, looks like an auto-complete change, possibly mixed in with more local signals.
