Mines also dropped out, last time it was a damaged fibre but assuming with so many people this may be a bt/sky issue

Any broadband issues between midnight and 7am could be essential overnight maintenance taking place which is carried out then to minimise disruption. There’s no pre-warning of this. See this pinned post at the top of the Broadband board from Sky which could be relevant any night this happens…

If you have an ONT box displaying a red light, see this further advice…

Hopefully it’s back up and running before 7am. If it’s not, post back in this thread and we can try to offer additional advice.

The forum has been seeing a lot of similar reports recently where overnight maintenance is causing the red LOS light. This means the ONT is not receiving any optical signal. The most likely explanation is that Openreach are doing a programme of work on the OLT units in the exchange that generates the optical signal which requires these to be shut down for a brief period.
