Widespread outage could last days after transport and communication networks disrupted, buildings plunged into darkness and millions left without electricity.
In the last place I lived, even the sewer lifting pumps also ran on electric and there was no backup. So once certain tanks and cisterns filled up and the pumps didn’t kick on, the system quit working. The fresh water tanks would keep fresh water pressure for 2-3 days (gravity fed) but could not recharge/refill without power. The whole system only worked if there was reliable electrical supply .
In that location every cell tower ran on its own backup gas generator, so after a handful of hours the gas supply would run out and each tower would also fall off until a technician could get fuel delivered.
