SACRAMENTO, Calif. (AP) – California’s preemptive power shutoffs to prevent wildfires have affected more than just lights. Some lost their phones, too. Data from the Federal Communications Commission shows 874 cellphone towers were offline during a power shutoff on Oct. 27. That included more than half of the cell towers in Marin County alone. On Wednesday, state lawmakers plan to question officials at telecommunications companies about how to better manage the outages during a power shutoff. Representatives from companies including AT&T and Verizon are scheduled to testify. Lawmakers questioned executives from the state’s investor-owned utilities in November.
