Apologies for your disconnecting broadband. Diagnostic tests from here indicate no area fault though your Hub has elevated upstream power levels along with a very high number of T3 timeouts. I'd like to arrange for an engineer to visit - please reply to my PM (purple envelope icon, top right of page) and I'll schedule an appointment for you.
Thanks for getting back to me. Appointment scheduled as per the details in my PM. I re-tested your connection first and the upstream power levels are still too high so it will be interesting to see if your disconnections abate following the visit. Keep us updated
