@alextetley To late now but sky are open 8am to 8pm tomorrow, call them from your landline phone by dialing 150 if it is working! A sky mobile is also 150 but just inform them you wish to talk about your broadband, and the service checker below by now if an area fault should be flagging the condition!
If you haven’t done it already use the below link to check to see if there are any broadband problems or outages nearby if enough time has passed for a fault condition to be displayed by the software test! This should determine if there's an identified fault affecting multiple households.
