Juneau and Douglas residents started reporting internet outages around 1 p.m. on Thursday.
About an hour later, Alaska Communications posted an update on its Twitter account, saying it was experiencing phone, internet and data outages and that its top priority was to restore service as quickly as possible.
Around the same time SnowCloud Services, a local internet provider, announced that a statewide outage was causing disruption in its service.
Several GCI customers reported still having a connection.
The phone line issue also affected the Juneau Police Department. For a short period of time, people needing to call 9-1-1 would’ve been unable to do so. City officials later said 9-1-1 was operational again, but that JPD phone lines were still down.
The city’s COVID-19 hotline was also unavailable for the afternoon, due to the phone problems.
Later in the day, Alaska Communications said on Twitter that the issue was related to an underwater fiber optic cable. Service was restored early on Friday morning.
This story has been updated. A previous version of this story said that the outage started on Wednesday and that service was restored on Thursday. It started on Thursday and was restored on Friday morning at 3:20 a.m. The story has been corrected.
