I very briefly worked at an ISP long after the days of dial-up were over. We had some super old servers on the network. These things hadn't been patched in forever, the OS was unsupported, etc. I think they were old Sun machines and Sun wasn't in business anymore. I asked what they were for and I was told there were still people paying for dial-up and their accounts were on there. They weren't actually using it, but the credit card auto payments were still going through and that was higher than the cost of the electricity. Nobody wanted to mess with it as long as people were still paying.
