Widespread outages and search for clues continue following Nashville explosion: "The damage is shocking"

Sweeping communications outages continued to plague large swaths of Tennessee on Saturday after a recreational vehicle exploded early Christmas morning in downtown Nashville. Meanwhile, federal investigators are searching for clues after the explosion that damaged dozens of buildings.

Police emergency systems across Tennessee and Kentucky, as well as Nashville's COVID-19 community hotline, remained out of service due to an AT&T central office being affected by the blast. The building contained a telephone exchange, with network equipment in it - but the company has declined to say exactly how many people have been impacted.
