No, obviously you have never lived through the aftermath of a hurricane or other large natural disaster. Cell phone and internet service die about 48 hrs after the power goes out because the standby generators at the cell towers and switching stations run out of fuel. Live tv and radio almost never go dead as they are considered lifeline services. Even POTS service goes out after extended power outages. We were somewhat luckey after Ike that water and gas services never did go down in our area. But they did in some. Power was out for 13 days. Cell and internet services were down for about 4 to 6 in there.
