I'm sorry to hear this.
I've completed a line test which hasn't detected any faults and your line is in sync at 27.5mb. What speed do you receive when running a wired speed test?
As far as I am led to believe, the MGDS is calculated from the achievable speeds on the line; and is used to indicate at what point the line is performing at less than an acceptable speed. It is also the speed at which OR will consider a fault MAY be present.
Thanks for the PM. The minimum guaranteed speed is now based on peak throughput speed, previously it was based on sync speed, that's why the MGDS differs from the speed given previously, apologies for any confusion
I fully understand that speed calculations are now achieved by a different method (since March 1st); so how do Sky and BT calculate the MGDS on my line to be 22mbps when TT only manage 16mbps - FTTC, copper and aluminium cable to the house. I am told that all these ISPs use the Openreach data.
Recent Openreach engineer visit, explained to me that TalkTalk cap standard fibre speed.
If by "standard" you mean the base product then every ISP does that, subject to the overall capabilities of the line. But I am not sure how this is relevant to the discussion here?
