We've noticed two sets of blips on some TT lines today -at around 10:16 and 10:21. We're not yet sure of the cause but are investigating.
Some lines dropped PPP and reconnected, whilst other saw a small amount of packetloss. We expect some sort of fibre break within TalkTalk, but that's only a guess at the moment.
