As part of the continuous improvement of our Major Incident process, we will be launching a new CityFibre Network Status page. From 2nd April 2021 all Major Incident notifications and updates will be posted here – Network Status Page

This will replace our current Entanet NOC page for Major Incidents ONLY. All Change Management activities, such as planned maintenance will continue to be updated on the NOC site.

Should a Major Incident occur, all communications throughout the incident will be posted here – Network Status Page

Please ensure you visit the new site from 2nd April 2021 to subscribe to receive any communications related to Major Incidents.

We will continue to monitor and improve the functionality of the status page on an ongoing basis.
