Summary Update:
 The Major Incident Team are currently investigating an incident that is causing significant service degradation and loss of service across the west and north of Scotland. We are working to identify the issue and resolve the issue as quickly as possible. Completed Actions:

 • CityFibre Network Engineering Engaged
 • Major Incident Process Invoked

Incident Start Time: 00:57, 04/05/2025

Cityfibre teams are working urgently to identify the cause and restore services as quickly as possible. CityFibre field engineers and third-party engineers are on site and have carried out OTDR (Optical Time-Domain Reflectometer) tests. These tests help determine how far network traffic can travel along the fibre before it fails, which in turn indicates the location of a fibre break. Initial results from CityFibre indicate that the fault lies within one of our third-party networks. We are now working closely with our third-party provider to confirm this and pinpoint the exact location of the break. Next Update: 13:00, 04/05/2025
