During the 15 Dec 2021 windstorm, the Colorado Springs gateway ran on battery power for over an hour until the batteries for the computer gave up. They should have lasted a lot longer. Will have to replace them with fresher batteries. Batteries for the radios did well. Power was out for about 3 to 4 hours. Internet went down for almost two days, so a WiFi hotspot was pressed into service and the gateway was back online as soon as power was restored. Surprisingly all antennas did fine.
