What the Hell?
That is one of the most incomprehensible graphs I have ever seen. I admit, I have never seen one like it, but with the color coding, it is nearly impossible to read.
But what it looks readily like to me, when one looks at the “Internet” group, there is a boatload of stuff going outbound.
If this were restricted to a local network with only a local server on site, a router, and all the machines connected ONLY to that isolated server) that did not allow outbound access, I expect one would not see the gold colored “Internet” disk.
Is that the way you would interpret this?
Yup, those are colored curved lines. No doubt about it.
