A person works on electrical wiring in San Juan, Puerto Rico, on Sept. 28. But that's not all: A report Wednesday by the Federal Communications Commission shows that cellular service has been all but obliterated in Puerto Rico as a result of Hurricane Maria. Although the area's two 911 dispatch centers are functional, as much as 91 percent of Puerto Rico's cell sites are out of action, according to the FCC. The U.S. Virgin Islands aren't faring much better, with 66 percent of their cell sites currently down. The following map released by the FCC illustrates how badly the mobile communications infrastructure in Puerto Rico is damaged.
