PORTLAND, Ore. (KOIN) — An RV fire in South Portland damaged the fiber optic cables on a utility pole, knocking out internet and cell service for many customers in the area for most of the day.

It’s not clear at this time what caused the RV to catch fire outside 2828 S. Corbett Avenue around 8 a.m. Tuesday. Three people live in the RV, but none were injured and all declined help from the Red Cross, Portland Fire & Rescue said.

Several fiber providers were affected and crews worked to restore service. It appeared most service had been restored shortly before midnight.

The RV is a complete loss. No further information is available at this time.
