Did Google Update Today?

My traffic numbers are way up for today. Normally Friday, Saturday and Sunday slow down and the beginning of the week I get a high amount of traffic.

For some reason most of my blogs are showing high traffic today. The source is Google search.

In checking my websites the traffic numbers are the same so this is only for blogs.

I have no idea if Google did an update or something, but I am linking whatever is going on.
