From the day I moved to aquiss (fttc) I’ve been hitting an artificial throughput cap somewhere in the network. Whilst I’ve extensively tested and ruled out anything my end (and indeed it only occurred upon migrating to aquiss and not anytime up to it). Disappointingly having made them aware of the issue they haven’t lifted a finger to help or investigate. It’s still above the openreach minimum so OR won’t look into it but I thought for the price they charge the ISP might be a bit better at investigating as there IS a definite cap I am hitting there somewhere that wasn’t there before. Fortunately fibre will hopefully be here in a few months so will only have to put up with it temporarily but in hindsight higher prices don’t necessarily mean better service so I would consider alternatives before going to aquiss.

Edited to add after the response- the reason there are no open tickets is because the ticket this was being discussed in was closed - with no help. Honestly at this point if I were still within cooling off period I would switch back.
