You’re lucky. Whenever we had storms or heavy rain the land line went out- for days. The phone company replaced the line over the years but it still went out in bad weather. I always worried that if the phone was really ever needed in an emergency it wouldn’t work. That made the decision easier a few years back to dump it.
In our area it is the cell service that goes out with the power, not the land line. We are in a rural area that the power company deems ‘unpopulated’ so they use their resources to get power back to the cities over an hour away. They know we will stay civilized if our power is out for days. The same can’t be said for the Obama voters in America’s cities.
