When there are broadband issues between midnight and 7am it's quite possibly going to be essential overnight maintenance taking place which is carried out then to minimise disruption as most customers are asleep. You don't receive advance notification of this from Sky or Openreach. Hopefully it'll be back up and running before 7am.

If it's not isn't, even if you’ve already tried it use this link to check to see if there are any broadband issues or outages nearby ~ (it doesn’t necessarily disclose a problem immediately and it can take an hour+ to update so perhaps try it again later).

This should determine if there's an identified fault, perhaps affecting multiple households.

If there aren't any then try running the line test here
https://www.sky.com/help/articles/broadband-diagnostic-start
You can also run the test via the MySky app on a mobile data connection.

Once completed, if it reports back that all is okay click on 'broadband' to run an updated test. If you get amber or red you need to follow the on-screen instructions.

If you’re still having problems you may need to contact Sky to report it. The easiest way is to dial 150 free from your Sky Talk landline if it’s still working.

This link provides information about the coloured lights on the various hubs

Working from home; Sky broadband being discussed here is a domestic service and whilst it's fine for those customers working from home to use it, they won’t receive additional or quicker support.

Bad weather; Adverse weather can also impact your broadband.

@Kay1685 the green flashing light indicates the hub cannot connect to the equipment at the exchange. If the lights on the ONT unit are also green it means your line itself is ok. If yiu have not done so report the issue to Sky if it happens during the day.

Coincidentally I had this fault myself last week which an Openreach engineer confirmed was caused by an issue on their equipment as unknown to me it was affecting one of my neighbours who was not with Sky. Full Fibre is far more reliable on average than partial fibre but can still have faults.
