Is google all over the place tonight?

Is it me or is google all over the place tonight? Whilst checking my rankings I came across a site with a page authority of 29 and 23 links from 5 domains ranking at number 6 for a competitive keyword! This site came from nowhere and I'm getting different results every time I search! Weird....

Some times Google does a shift in rank, a poor site can come up in the ranks and then instantly go back down. If the same site is still their in a week re investigate.
