Broadband turns off itself

[Glyn15]

For the last two nights my broadband has stopped working. The centre light on the router is out and the two on either side are on.

It came back on this morning at around 09:15 and has gone off again this evening at 21:00.

Sky advised last night that there was an outage but tonight the checker says it's all fine. Any help appreciated.

@Glyn15  How long has your internet been down tonight? Is it longer than 1 hour?

Broadband went off at about 8:00 this evening and last then came back on at about 09:00 both yesterday and today. I managed to contact Sky and spoke to a human who advised that this was most likely to be an issue with the Open Reach side so Sky Wii hopefully have that sorted within, they say, 72 hours. Hopefully they will. Thanks for the response.
