Comment 5 days during the aftermath of Hurricane Ike (Score 3, Informative) 328
When Hurricane Ike caused massive wind speeds and damage to the midwest, we were without power from Sunday to Thursday due to all the downed power lines all over the state. I ran a laptop, wireless router, and cable modem off of a 300watt inverter plugged into my car the entire time. I had to go outside and run the car for 30 minutes every 12 hours to keep the battery charged but I never once lost internet access. The neighbors couldn't believe I still had working high-speed internet access in that kinda situation.
