This issue is now resolved.
At 10:53 BT experienced difficulties with hardware in the Sheffield node which affected 20cn DSL users in the surrounding area.
The difficulty was as a result of faulty card impacting routing across multiple devices.
Service has been restored as of 12:21pm by completing a remote reset of hardware.
Sorry for any inconvenience this may have caused.
