Bear in mind that this is only a BT Retail forum, so only BT Retail users would be interested.
Have you looked at the BT Service Status to see if there are any issues?
Provided they get their phone and broadband from BT Retail, they are welcome to register and post on this forum.
Bear in mind however, that BT Retail do not provide or maintain the external network, this is done by Openreach.
If a group of people on the same street cabinet with BT Retail, all have service issues, then it is possible for BT retail to bring it to the attention of Openreach.
