You click a link to a news site, to read an article that seems interesting.
On the page that loads there is the article, but also, somewhere on the right, often near the bottom, there is a small video player. Inexplicably, it was not blocked by your ad-blocker.
It is auto-playing a news video that is not connected to the article. Sound is often on.

@ashfurrow @rysiek Woo! Actually, you can probably watch your nginx access log to get an idea. If you use Netdata, you can get graphs from that.
@Gargron @ashfurrow also, goaccess is great for watching your nginx logs. Did this many times when we published something big at $OLDJOB.
@rysiek ah, a pronounced increase!
