** Update: 07/06/2025 6:11 PM EST **

Fire crews are currently conducting controlled burns along the highway and the fire is active on both sides of the road. Due to safety concerns, the fiber provider has been unable to assess potential damage to infrastructure. Repair crews continue to remain on standby and are pending clearance. They are expecting rain to start in the area which may help reduce fires. The provider does not have access to facilities and is unable to make any reroutes. Restoration efforts will proceed as soon as conditions allow. No ETR is available.

** Update: 07/10/2025 **

The Fairbanks primary circuits are active, but those links are intermittent as the splicing and telecommunications crews continue with repairs. Network link speeds are expected to be intermittent while the extensive fiber repair is ongoing and the data coverage shows improvement.
