A large internet disruption affecting communities across parts of Northern and Central California on Wednesday was caused by a vehicle crash, officials say.

Xfinity says a vehicle struck a utility pole around 9 a.m. Wednesday in Rancho Cordova, disrupting both Xfinity and Comcast Business service.

The communities affected include customers in Clovis, Elk Grove, Fresno, Lodi, Los Banos, Madera, Mendota, Perkins, and Rancho Cordova.

Xfinity crews were still at the scene late Wednesday night trying to repair the problem.

Restoration is expected by around 8 a.m. Thursday, but Xfinity is urging customers to check for updates at xfinity.com/status.
