Something seems off with the counting of unique visitors today. My site has a pretty consistent amount of visitors per day. Today it seems that it just stopped counting unique visitors about 3/4 of the way through the day. I run two separate analytics platforms and they are giving accurate visits/views. A-ads is showing much less and I'm pretty sure my none of my visitors would have visited any of the other publishers sites because my niche is different than most.

Any idea why this might be?

Thanks in advance.
