It's common for the Googlebot to crawl sites at an accelerated speed after an update. This has been happening to my site today... part of the day the crawl rate has been over 5x the normal rate.
I don't think this is outside of the norm. Actually, referrals from Google have been more consistent hour over hour than it has been in weeks.
On a different note, Analytics reports that traffic has been down for my site Saturday because of a reduction in visitors from London. I hope this means that the change has rolled out outside of the U.S. now and I haven't seen much of a difference.
I'd love to hear from others regarding what their Analytics Intelligence reports and if they have seen a change in the number of referrals from outside the U.S.
