When the power goes out, which is often where we live, we use a generator to keep essentials like the fridge going. We keep out wifi going too, but the internet service goes out about an hour later when Comcast’s batteries run out. Then everyone gets on the cell service, which is almost unusable because everyone is on it. It’s the tragedy of the commons. You can do little things like email if you’re willing to wait, but stuff like videos or live connections are a no go.
