Sky is experiencing service issues, leaving thousands of broadband customers without internet access.
Users located in the south east of the UK appear to be the hardest hit.
The service issues started early this morning, at around 05:30am, according to DownDetector.
“You might not be able to get online or make/receive phone calls due to a problem in your local area,” Sky has said.
The company has also listed Baldslow, Battle, Beckley, Bexhill, Brede, Brightling, Brookland, Castleham, Cooden, Crowhurst, Guestling, Hastings, Iden, Lydd, Ninfield, Northiam, New Romney, Peasmarsh, Rye, Sedlescombe, Staplecross, Wittersham, Eastbourne, Hampden Park, Alfriston, Newhaven, Peacehaven, Polegate, Pevensey Marina, Pevensey, Seaford and East Dean as affected areas.
The Sky Help Team says it has engineers working to resolve the issues for customers in Sussex.
“Update: East Sussex. Due to extent of the damage. Engineers are still working on repairs. Updates to follow. Sorry for any inconvenience,” it tweeted earlier this morning.
It then followed up with: “Update: Sussex – Engineers have located 7 separate breaks in the Fibre cables & are working to repair damage as quickly as possible.”
The account is also tweeting affected users directly, and has told some of them that its engineers are “preparing cables now for splicing”.
Sky says its engineers are “making good progress”, and that normal service will be restored in Sussex this evening.
