I'm in a Seattle suburb and we had a two-day blackout a few years back. Cell reception worked fine for 12 hours but then went to 1 bar. Presumably the closest cell site ran out of gas on the backup generator and my phone switched to a site outside the blackout zone. What is wild was that this was entirely localized! A single substation affecting maybe 20,000 people. How many cell sites were affected, a dozen? And still T-Mobile couldn't manage refueling. In a country-wide crisis we would be totally boned.
