C Spire routinely takes precautionary steps and puts restoration teams through various training and test scenarios and masses equipment and materials to protect critical network facilities and cell sites. The company uses back up batteries and diesel generators at mobile sites and switching centers and makes arrangements for replacement fuel supplies in case normal fuel delivery options are interrupted by commercial power outages or road closures.
The company operates multiple hurricane-ready "hardened switches" that provide added protection and service assurance for customers. The high-tech telecommunications switching facilities are designed to withstand a Category 5 hurricane with winds up to 155 miles an hour, connect millions of calls, wireless data transmissions, video content and other critical services daily for consumer and business customers. In addition to hardened and reinforced shells, the all-steel and concrete buildings house large-scale 500-kilowatt diesel power generators, a grid of back up batteries and other redundant back-up systems, operations and technologies.
