I need to update as I just dug deeper. On this 10+ year old site:

This week vs the last two years. Bing has accounted for 35% of the sales this week, 0% last year. Bing visit duration is way up on average, the bounce rate is down 14%. Google the bounce rate is down 4%, visit duration down. It recovered some today.

It appears we saw a statistically relevant shift towards Bing this week. These fluctuations are hurting google. Our cpc clicks are down during the flux days too.
