Several thousand Comcast Xfinity customers in Berkeley, California, suffered Internet and TV outages on Sunday night (September 24).

As reported by Berkeley Side, the outages are believed to be be due to vandals who damaged multiple lines of fiber optic cables, leaving between 5,000 to 6,000 impacted.

“Comcast technicians are on site and have begun working immediately to identify, repair, and restore services to customers in the region,” said Jon Koriel, a spokesperson for the company.

“Our teams are currently working with local authorities to determine the cause of the vandal act and to prevent further acts of vandalism.”

Comcast provides Xfinity Internet services to many in Berkeley.

Xfinity has suffered outages in the past due to vandalism to its infrastructure.

Last month, the company blamed vandals for an outage that impacted customers in parts of Napa and Sonoma County, both also in California.

Comcast-owned Xfinity was also hit by a major outage earlier this year during the Super Bowl after the damage was caused to a fiber optic cable.

The outage took place in Philadelphia, the home city of the Eagles, who were playing in this year's Super Bowl event.

It took place before the game kicked off, leaving a few thousand Comcast's Xfinity Internet and cable service users without pre-game coverage, although the company claimed the bulk of the customers regained coverage by kick-off time at 6:40pm.

This incident was similar to one the previous year, when an outage in Oakland, California, caused issues for around 30,000 people during an NFL game between San Francisco 49ers and the Los Angeles Rams. That outage was due to someone shooting the fiber cables.
