In the U.S., it's common to find business Internet connections that depend on AC power to operate, which go dead during a power failure. Since most elevators here also run on AC, any widespread power failure leads to tens or hundreds of people stranded in elevators, and, if the emergency phones in those elevators require Internet connections to work, also unable to call for help.

The figure was higher than the 644,000 lines expected by a consensus of Wall Street analysts, suggesting the wireless market is showing signs of health despite economic uncertainty. https://thedesk.net/2023/01/att-verizon-t-mobile-retail-postpaid-wireless-adds-holiday-2022/ -- (Pleae remove QRM for direct replies)

Specifically, AT&T said it now expects its wireless service revenues to grow "at least" 4% during 2023. That's an improvement from the "low single digit" growth the company forecast during its analyst day early last year. https://www.lightreading.com/5g/after-verizon-lowers-expectations-atandt-raises-them/d/d-id/782872?_mc=RSS_LR_EDT -- (Please remove QRM for direct replies)
