Frontier's Post-Bankruptcy Story

Frontier Communications filed for bankruptcy in April 2020 and emerged in May 2021 with a singular strategic mandate: replace their entire DSL and legacy copper network with fiber. The rebuilt Frontier is a different company from the slow-DSL provider that preceded it.

Their rebuild uses XGS-PON throughout, giving them 10 Gbps symmetric infrastructure capable of the 5 Gig plans they now offer. Frontier's 5 Gig plan at $155/mo is priced competitively against other providers' multi-gig offerings. For homeowners in their footprint, Frontier Fiber is a genuinely compelling fiber option that existed before AT&T Fiber arrived.
