A fibre link cut south of Enterprise is causing a telecommunications outage for most of Friday but the issue is expected to be restored by the evening.
The territorial government put a notice up on social media just before 10 a.m. on June 12.
The notice states that disruption along the Mackenzie Valley Fibre Link may affect telecommunications throughout NWT, including 911 service or any landline emergency (1111/2222/4444).
Customers with cellular service with Telus, Iris and SSI cellular may prevent emergency numbers in the territory.
People with Bell cellular and Northwestel, however, will be able to call NWT 911.
"This is not an issue of 911 but of the telecommunications infrastructure," states the notice.
The NWT RCMP also issued a news release stating that service may be disturbed as people try to reach out to the RCMP detachment as well as Operational Communications Centre (OCC) in Yellowknife.
Fibre line cut south of Enterprise
Police say that they had been notified by Northwestel on Friday of a fibre optic line cut south of Enterprise and that the communication outage is affecting wireless telephony services across the territory.
"Until the repairs are complete, calls to the local detachment may not go through, or calls may not be automatically forwarded to the OCC," states the release.
"If the public require police assistance, we ask they attend the detachment during regular working ours. In most detachments this is 9 a.m. to 5 p.m, Monday to Friday.
"Our technicians are working with all partners to resolve this situation as soon as possible."
