When's this work happening?
This afternoon, 18th November.

What does it affect?
Traffic shaping on our 'Up to 20Mbps' 21CN ADSL2+ network.

How long will it take?
A couple of hours.

What does the work involve?
One of our hardware vendors has proposed that we make some configuration changes to some of our edge routers to try and fix a recently identified problem causing intermittent latency spikes on our ADSL2+ network.

Is it likely to cause problems?
It shouldn't cause any noticeable problems although there might be a five minute period during which 21CN customers will only be able to connect to the gateway known as pcl-ag04 (you can normally connect to thn-ag2 as well). There is a slim possibility that the change could negatively affect some customers' traffic management profiles. If this does happen we'll announce further details during the time.

Is there anything else I need to know?
We're only applying these changes to thn-ag2 for the time being. We will then monitor the platform overnight and if considered successful, will apply the same change to pcl-ag04.

Kind Regards,
