We would like to advise you of the upcoming 21CN (21st Century Network) upgrade works which will be affecting customers BT IP Stream DSL connections over the coming weeks and months.
 
The work is required to allow DSL customers to benefit from developments in next generation technologies including higher bandwidth speeds.

 
Whilst we will aim to make the change-over as smooth as possible, there will be some disruption to the Broadband service on the day of the upgrade.  This will typically mean that end users may be unable to connect to their Broadband service for between 15 to 30 minutes.  Unfortunately we are unable to specify any specific timings of when exactly this will be happening on the day itself.

 
From the time the customers broadband automatically reconnects to the service, the new 21CN line will be rigorously tested to ensure it will deliver services of the highest quality both now and in the future.  During this period customers may experience drops in connection or a slower line speed for the first 4 to 10 days.  Once the stabilisation period has been completed the Broadband service will continue to work as normal.

Regards,

Node4 Support
