Frontier Outage - Los Angeles Area

Update timeline

1. identified Aug 21, 2025, 08:19 PM UTC

   TPx customers in the greater Los Angeles area may be experiencing intermittent service interruptions. Our investigation has correlated these issues to the Frontier Network. Frontier initially suspected a fiber impairment due to low light levels between two central offices. A fiber repair crew was dispatched, and a section of fiber was replaced. Following this work, Frontier identified a secondary issue with a failing card. This failure is causing high receive span loss between the two offices, resulting in instability on the affected link. We are actively escalating this matter with Frontier leadership to obtain a status update on the card replacement. At this time, no estimated restoration time has been provided. We will continue to provide updates as more information becomes available. If you believe your service is impacted, please open a support case with our technical teams at www.tpx.com/support.
