How is copper more reliable than fibre as an emergency communications medium? I guess 1800s technology suffices to transmit something over copper, so there's that.
Edit: also domestic routers are buggy and unreliable and need to be restarted regularly
Having to worry about the CO power, house power, device power, and the power going to towers is a little much for my taste.
> ""Analogue networks have been in operation for decades and have reached the end of their serviceable life. The telecoms industry is finding it difficult to source the parts required to maintain or repair connections as suppliers are no longer manufacturing them. Ofcom, the telecommunications regulator, reported that 2023 saw 20% more service incidents on the PSTN compared to 2022, resulting in a 60% increase in the number of service hours lost to customers

If you have other devices connected to your phone line, such as alarm systems, telecare devices or fax machines, you should take steps to ensure they will continue to function correctly.
...
The analogue landline carries a low voltage power connection directly from the telephone exchange, which is sufficient to power some basic corded handsets without needing to plug them into the wall. This means that in the event of a local power cut, these corded handsets will continue to function as long as the telephone exchange still has power.
Digital landlines cannot carry a power connection, which means handsets and routers must be powered from your home power supply, and they will not function in a power cut unless you have a backup power system such as a battery or generator. Telecare devices connected to a digital landline network may not work during a power cut.
Communications providers are required by Ofcom to take all necessary measures to ensure uninterrupted access to emergency organisations for their customers, including in the event of a power cut."""
