Sky Broadband users lose internet access if they are not set to use the ISPs default choice of domain name server. Customers will have to request a firmware rollback, and then wait up to a week, before they can access the internet via their third-party DNS settings again. The Reg was contacted by a Sky subscriber who wants to remain anonymous. They lost internet access on Friday morning and were told it was due to a firmware update which went out overnight on Thursday. Initial promises of a fix within 72 hours were then amended to between three and eight days.”]
