So far, cellphone networks have weathered Harvey

NEW YORK (AP) — Roads, refineries and other infrastructure have taken a beating in the Texas and Louisiana regions hit by Harvey — but cellphone networks so far remain largely functional.

One reason: Big carriers brought in supplemental equipment and backup power and turned to drones to diagnose problems.

Four Gulf Coast counties northeast of Corpus Christi, Texas, had more than half of their cell towers knocked out earlier in the week, but crews have been able to restore many of them. As of Thursday, one of the most heavily hit areas, Aransas County, reported 32 percent of its 28 towers out.

That's down from 95 percent right after the weekend's storm, according to data from the Federal Communications Commission.
