Tracing a call is instant. It took longer back in the days when there were physical switches, but that's been a long, long time ago.
Yup. Back in the days of analog phone exchanges, you literally had to send a guy to check electrical connections between lines. Which is why it took time and which is why they encouraged the people to keep on the line as long as possible.
Digital exchanges added call tracing as a design requirement. Everything gets logged. Even if you spoofed or blocked your number, the phone company knows what you did. They are the Phone Company.
I can just tell that whenever Twitter's user interface has weak attempts at humour, it was put there during the previous ownership, and that just makes me sad.
Like when you delete your account the final message says "#Goodbye", I was tearing up, thinking, like, shit, Musk really fucked everything up, did he?
