We saw a number of BT lines drop at around 16:05. Most have reconnected.
Looks like this affected other ISPs too. Also looks to have affected lines in the south-east of the UK.
Whilst many lines reconnected after a minute or two, some are still offline. Customers still down could try switching off their router for a couple of minutes then retrying. (High demand in the BT network can cause problems when many lines to to reconnect at the same time)
Most of lines that are still offline are those in EC postcodes - but the majority of lines that dropped initially are back.
We've given BT a list of circuits that are still down. (The number of lines still down is about 15% of the total number of lines that dropped initially)
The remaining lines reconnected just before 5PM
This was an incident at BTs FARADAY location affecting multiple ISPs and many broadband lines in the south-east of the UK. BT have not yet given further details about the cause.
