[Broadband] High Latency in East of England areas from 11AM - Closed
Details
Posted: 05 Sep 2017 12:01:04
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.
