Some TalkTalk connected customers have high packetloss on their lines from around 3pm today. These lines are in the Chippenham/Bristol area. If affected you'll be experiencing slow speeds.
TalkTalk say "NOC & Network engineering are currently investigating congestion and packet loss across the core network." More details to follow.
Problem looks fixed as of 18:15
(This also affected some other circuits in other parts of the country.)
From TalkTalk: Root cause has not currently been identified.. The (TalkTalk) NOC engaged Network Support, who investigated and added a new link in order to alleviate congestion. The B2B Enterprise team are currently retesting with the affected customers and initial feedback indicates that this has resolved the issue
