At my first real internet-related job (admin/support at an ISP), over 20 years ago, I got an urgent page from a client.
I called them back to see how I could help.
Their problem: they were stuck on the Internet.
I don't remember my proposed solution, I think I tactfully suggested turning the computer off and on again.
(It took a lot of empathy to figure out what they meant: a screen spammed with popup ads. Probably from dodgy pron. I learned more from that call than they did!)
