After 10+ years of waiting on an Exchange Only Line I have been finally upgraded to FTTC here in Central London, Commercial Street Bishopsgate Exchange. Yesterday I saw it switch to Available from Planned.

I have also just located the cabinet earlier ago today and it is exactly located in 46 Frostic Walk, Shadwell, London E1 5LT.
It is approximately 0.2 miles to my home in E1 6DJ ~ 321.869 meters. Now I have a couple of questions to ask. According to the checker my lowest expected speeds should be between 64.8 - 68.2 Mbps with the highest at 80 Mbps.
Iím worried that with a 322 meters or so copper cable length my internet might not be stable to maintain those speeds. What if the internet drops out and the line cannot cope with such speed? Will the connection speed drop to below the lowest levels?
As Iím aware it is not about just getting those speeds, if noise margin drops and disconnects DLM will re-sync to a lower speed and the speed may get to something below the lowest estimate.
Iím still with Plusnet ADSL and already paid year upfront in advance on January. I have until January 2020 for the 12 month contract to end.
For example with ADSL I got once 18.07 Mbps in speed test but at 3dB noise margin. Line could never maintain stability! In both cases with Sky and Plusnet I had to tell them to increase the SNR to 9dB manually for the connection to be stable. Only at 12 Mbps ~ 9dB noise margin my connection is stable and that's between a maximum of 34-56 days. This has always been my headache, thatís why I am worried that FTTC may carry on the same problems if cabinet is not so close to my buildingÖ
Can someone tell me from your experiences living around 300-400 meters away from your street fibre cabinet whether you are able to sync at such speeds without connection dropping out? What's the highest connection up-time you get on average? Obviously without me ordering, I will never know what to expect. But I'm afraid what if the internet drops out and the line cannot cope with 64-68 Mbps speeds and drops to something significantly lower than that?
Do you think I will be able to quit the ISP penalty free? Iím more positive about the 35 Mbps package as that will be more friendly on the line. FTTC will be my only option for now as my building management team seemed to have refused wayleave consent with Hyperoptic last 4 years as discussed previously last year...
