@AndyStubbs the stats dont tell us very much as the hub was restarted just before you took the stats. If the hub is not restarting on its then it is likely to be faulty but if you restarted it yourself that doesnt apply.
Line drops on copper lines are not uncommon especially in periods of bad weather and Openreach are often reluctant to take action as their automatic DLM system is designed to intervene dropping speeds slightly by increasing the noise margin and improve stability. There are signs that is happening on your line as speeds are slightly below 80Mb/s and the noise margin is slightly high at 6.4dB but likely to be well abovecthe guarantee.
It is only where that system cannot stabilise the line without dropping speeds below the guaranteed speed for the line or drops exceed 10 a day that Openreach will definitely accept a fault report from their customer Sky. These are the SLA for domestic lines you are buying, the fact you use the line for business doesn't change that unfortunately. It is worth reporting the issue to Sky if you do try to use the Sky Talk line as if that is crackling Openreach will be more willing to sort the issue. Dialling 150 on that line gives you a free call.
