I have a network-wide pi hole and I noticed that it requested activity.windows.com, a url blocked by my pi hole, even while my pc is suspended. I pinged 10.0.0.217 and it is currently unreachable. So, somehow, windows pc’s turn on networking, phones home, and turns off even while suspended.
Creepy behavior
The thing is, the device was in suspend for a couple days now.
Modern sleep modes are internet connected, with the intent to allow systems to perform updates while sleeping.
I don’t like it but that’s how it’s designed to work.
