Before stats showed about 7 to 9 percent of the site's traffic was from mobile; but today at around 9AM Eastern US, 67% of the traffic was mobile:
This is a huge change in Google search referrals and site traffic patterns.
Need to do some analysis and see what is going on, seems too "strange" to have such a dramatic change / shift.
My first indications are we are seeing an increased amount of mobile activity from China, which I suspect might be bots indexing site content using a mobile user agent, unfortunately.
