I am seeing the same spike in GA too since Oct 30. It now tops the keyword list whereas before it would be in 4th or 5th spot. Looking at the data it is mostly from US.
My traffic has also decreased since Oct 30 a bit so not sure if that is Seasonal related, weather (power outage in New England) or related to G tinkering.
