We have noticed congestion one some of our TalkTalk circuits. customers affected are seeing an increase of latency and some packet loss. We have reported this to TalkTalk and as soon as we have an update we will update this post.
Here is an example graph
Update from TT We lost multiple 10G circuits to our transmission network due to a BT fibre break in the Ipswich area - Openreach have applied for a MBORC on the issue. There was congestion in the Ipswich and Cambridgeshire wider area as a result which was resolved shortly after midnight.
