Noticed traffic suddenly lower, but looks 'real'

I noticed the Netlify Analytics to my sites (including which is Netlify domain are suddenly a lot lower, but the traffic looks like real (not bot) traffic.

My question is whether something has changed on Netlify’s edge network that would account for this, or if there is just a large drop in traffic to my site. I’d be quite happy if the difference in numbers were due to an increase in accuracy.

EDIT: Seems to be back to normal, so this can be closed.
