We have identified a small number of TalkTalk connected circuits that have 1-4% packetloss in the evenings between 7pm and 9pm. We have worked with TalkTalk NOC and have helped them to identify a link running at full capacity within their network. Work is still ongoing to fix this.
To aid with TalkTalks investigations we have shutdown our interconnect in Harbour Exchange to TalkTalk. We still have plenty of capacity in Telehouse so this work is not service affecting.
TalkTalk say: "NOC troubleshooting has identified that one of three 10 gig circuit between the LTS and the LDN at hex is reaching capacity between 19:30 and 21:30hrs and is the root cause of the packet loss."
See: https://aastatus.net/2454 for details regarding testing the new TalkTalk network which will resolve this.
packetloss on TalkTalk connected circuits has increased over the past day or so. We're happy to move customers to trial TalkTalk's new network, do get in touch with trial@aa.net.uk
TalkTalk have done some work on their side which should help reduce the low levels of packetloss that some lines are seeing.
Work that TalkTalk have done recently has helped with congestion and we are now seeing far fewer lines with congestion.
We don't yet have a date when we'll move all customers across to the new network. We do hope this will be before Christmas bust due to the holidays it may be early January.
The congestion problem has been resolved. The longer term option of moving our customer base to TalkTalk's new network will happen in January 2018. More details of this will be posted nearer the time.
