As with other internet service providers that have expressed an interest in the UK division of Tiscali, Sky appears to have taken a step back from the deal before it really started and, once again, it is an issue over the value of the business that is the stumbling block.
In February, it will be a year since the ISP commenced a strategic review.
Vodafone looked like the best option until it withdrew from negotiations in June.
Then in August Tiscali received a bid of £600 million from the Carphone Warehouse which it flatly rejected.
The price now is estimated to be around £450 million for Tiscali and its 1.8 million customers, but it looks as if Sky is disputing the value of the company and is thinking it all over once more.
