A massive drop on both Saturday and Sunday, in fact my two lowest impressions days of the year barring Easter Sunday.
Exactly the same with my site (UK).
I have had a website jump around 200+ places to #5 today. This is a 6 month old website, finally ranking for it's term.
Do you think another update is on route?
