Virgin Media said it is working on a fix for the outage that is affecting people in Lincoln and the surrounding area since Friday night.
Emma Hutchinson, a Virgin Media spokesperson, said: “A power fault in the area has affected our services.
“Our engineers are on site and have been working through the night to restore services.
“We’ll have everyone back online as soon as possible and we apologise for any inconvenience.”
Virgin Media’s online service status pages is showing customers a fix is not expected until Sunday morning.
As previously reported, hundreds of people are having problems with their broadband, TV and phone services since 7pm on July 4.
The entire Lincoln area has been affected. Readers from Grantham, Gainsborough and Sleaford also reported similar issues with Sky broadband and phone services, which use Virgin’s equipment.
A Virgin Media engineer explained that the fault is due to a fire that damaged cabling in Nottingham on Friday afternoon.
