Continuation of service from Excite@Home had been in doubt after Judge Carlson ruled that the company could cease service from midnight on 30 November.
The company's creditors had filed for the ability to shut down operations as part of their continuing search for a buyout or to enable them to renegotiate contracts with cable network operators.
Following the breakdown of takeover talks, the company pulled the plug on AT&T in the early hours of 1 December. The move left 850,000 AT&T subscribers without cable Internet service.
However, service has remained largely uninterrupted for other cable network operators.
