We are seeing very high latency - over 1,000ms on many lines in the East of England. Typically around the Cambridgeshire/Suffolk area. This is affecting BT circuits, TalkTalk circuits are OK. We are investigating further and contacting BT. We suspect this is a failed link within the BT network in the Cambridge area. More details to follow shortly.
We're currently awaiting a response from BT regarding this.
BT are now actively investigating the fault.
As expected, this is affecting other ISPs who use BT backhaul.
Latest update from BT:- "The Transmission group are investigating further they are carrying out tests on network nodes, As soon as they have identified an issue we will advise you further. We apologies for any inconvenience caused while testing is carried out."
BT have confirmed that a card in one of their routers was replaced yesterday to resolve this.
