Thousands of Virgin Media customers lost their digital TV service across the West Midlands.
The problem began in Wolverhampton where a 6pm “router failure” took until nearly midnight to fix.
Virgin today acknowledged there had also been further problems in Witton, Birmingham and Guildford, near London, with further viewers reporting other problems in Moseley.
A Virgin Media spokesman said: “At 6pm yesterday evening, customers in the Wolves area experienced a loss of their digital TV service. This was caused by a router failure. Engineers were dispatched immediately and the majority of channels were restored by 10pm with the remainder back on around midnight.
“We are sorry for any inconvenience this may have caused.”
A message on Virgin Media’s automated customer service hotline at 8am today said: “If you are calling from the Birmingham, Dudley, Wolverhampton or London areas regarding a fault on your digital television service, please be advised that our engineers are aware of the problem and working to resolve it within the next five hours.”
Moseley customer Roy Gillard said: “Virgin went off-air from around 6pm last night and still hadn’t been restored by the time I went to bed at 11.15pm.
“Their service lines were unobtainable or engaged all the time, although a recorded phone message was posted.”
Key programmes viewers would have been missing last night included ITV1’s Coronation Street, I’m A Celebrity, and part four of the Channel 4 series, The Queen.
But a Virgin spokesman today said: “Some customers in Birmingham are still without their Virgin Media services due to a commercial power outage unconnected with last night’s problem.
“We are currently investigating, with engineers on site, working on a remedy as a high priority.”
