From TalkTalk: Our NOC advised that alarms cleared at 09:45 and service has been restored. Our Network Support has raised a case with Axians (vendor) as there appeared to be an issue between the interface cards in the NGE router and the backplane (which facilitates data flow from the interface cards through the NGE). This incident is resolved and will now be closed with any further root cause with the Problem Management process.
