This is not good news!
The fault detialed on the last message is clearly more serious than was first thought. BT is currently sending this message to their customers reporting a fault in North Perrott.

BT here. Our reference is: IMP-111266963. Thank you so much for the response. I have checked that this line is impacting with major service outage in your area issue and that’s why this fault is associated with an incident: AF-IE-1898344969 currently affecting 309 services according to this I can see main issue is e/side breakdown and team already working on this and provided targeted fix date as on 17/02/2023. We are trying to get this fixed soon but it will take time. Also please know that as this is declared as a major service outage for 309 other servoces as well we will not be able to compensate with a rental rebate for the same. We regret for the inconvinience.
This is a similar message that was given out by TalkTalk earlier in the week except that the target fix date has been extended to 17th Feb!
This is clearly a major incident that will take time to fix but I’m making enquiries to see why service prividers are not obliged to pay compensation and if not, whether customers can persue OpenReach instead?
Please post any relevent information that might help other phone users with problems at the moment.
