We have identified some TalkTalk back haul lines with congestion starting around 16:20 and now 100ms with 2% loss. This affects around 3% of our TT lines. We have techies in TalkTalk on the case and hope to have it resolved soon.
"On call engineers are being scrambled now - we have an issue in the wider Oxford area and you should see an incident coming through shortly."
Engineers fixed the issue last night.
