UKOnline's future has been in doubt for awhile, though I don't quite know why they're taking so long to make a decision about it. The problem stems from how BSkyB now owns Easynet and thus UKOnline, which effectively puts the ISP into competition with Sky Broadband.
Naturally BSkyB would prefer that not to be the case and sometime ago last year took the decision to halt new signups while they mulled over what to do. It's been that way ever since. It is not, as they have claimed in the past, a technical problem with the order system.
However existing customers should be under no threat, they’ve just “pulled a Bulldog Broadband” by leaving the service/website in place while effectively closing it to new users.
