Insane Traffic Anomaly with Users

My site is seeing a crazy increase in users from March to June and beyond. Historically, we'll see anywhere from 220k-550k users per month. Right now we're seeing 1.5M users with only 3% returning and 90+% direct.

What is going on?

On one of our higher trafficked sites, we're seeing this code, can anyone tell me if there would be anything causing this? I know the traffic is not accurate.

var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
ga.src = ('https:' == document.location.protocol ? '//ssl' : '//www') + '.google-analytics.com/ga.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
})();
