The weirdest thing just happened. I was on https://beej.us/guide/ and I removed the last part of the URL to make it only https://beej.us and I pressed enter. This took me to cnet.com. I have never been on cnet.com before. I have no idea how this happened. Does anyone have a clue? I'm using Firefox if that matters. Did a web server somewhere get hit by a cosmic ray or is beej's server infected by something? This is super weird. When I try to do it again it just takes me to beej's site as expected.
I couldn't reproduce, but I note the background image changes on reloads. Perhaps beej is hotlinking, and one of the images is based on cnet, who redirected to themselves?
