Hundreds of households in York lost their broadband last night (Wednesday).
A Sky Broadband outage caused widespread problems in the city and beyond.
The problem affected postcodes including YO23, YO24, YO26, YO31 and YO43 according to an outage site.
Sky published a notice which said: “There’s an outage on our network. If your broadband isn’t working, you might be affected by a large outage on our network at the moment.
“We know it’s frustrating, but you don’t need to call us. We already have engineers investigating to get you back up and running as soon as we can.”
But people were critical about the lack of communications from Sky. One of those affected said: “You spend ages going through diagnostics because your mobile signal is shocking in the house and there is no WiFi only to find it isn’t your problem.”
