We're seeing low levels (1-5%) of packet loss and low throughput (eg 16-60 variable on a 70M VDSL) in the evenings on some TalkTalk connected lines in the SO postcode area. We've passed the affected lines on to TalkTalk for them to investigate further.
TalkTalk are unable to see any congestion problems at the moment -we're investigating further.
Further investigation shows that although the examples of lines with packet loss in the evening are all the the SO postcode areas, they are all diversely connected through the TalkTalk network - different DSLAMs, Multiple switches and backhauls and also different BNGs across three exchanges.
We'll investigate these lines as individual faults for the time being and will close this status event.
We've re-opened this as TalkTalk are now investigating a possible switch that is 'maxing out' at peak time.
From TalkTalk: "We are in the process of delivering additional capacity to alleviate the issue we have seen here alongside migrating customers to alternative cable links. This is an ongoing process our incidents are hopeful will be completed before Christmas"
Note: This issue is affecting a small number of lines in the Southampton postcode area.
TalkTalk moved some of the traffic off the congested cable link at Southampton exchange and now confirmed resolution to this incident
