Fiber Line Damage Disrupts AT&T and Xfinity Internet Service in Oakland

Recent damage to fiber lines has knocked out internet service for AT&T and Xfinity customers in Oakland, California, according to verified reports from SFGATE and Comcast corporate communications. The outages stem from a combination of copper theft and gunfire damage affecting critical telecommunications infrastructure across multiple neighborhoods in the city.

SFGATE reported on April 23, 2026, that copper theft is actively disrupting internet service across Oakland neighborhoods, with thieves targeting fiber optic cables for their copper content. This follows a separate incident confirmed by Comcast on February 26, 2023, in which multiple gunshots fired in Oakland damaged Comcast fiber lines, resulting in service outages for residential and business customers in affected areas.

AT&T provides outage information through its official service status page, where customers can check for disruptions impacting wireless or internet service in their area. Similarly, Xfinity offers a status map tool that allows users to verify potential outages affecting internet, TV, or phone services in specific locations.

The recurring vulnerability of Oakland’s telecommunications infrastructure highlights ongoing challenges in maintaining reliable service amid criminal activity targeting physical network assets. Both copper theft and violent incidents pose direct threats to fiber optic lines, which are essential for delivering high-speed internet connectivity to homes, and businesses.

Residents experiencing service issues are advised to consult official outage maps from AT&T and Xfinity to determine whether their area is affected and to follow recommended troubleshooting steps provided by each provider. As of the latest available reports, no official restoration timelines have been published for the impacted zones.
