here in thornaby (stockton-on-tees)
we were on 3 x 64 QAM , 12 lockable ds cisco ubr before the update with congestion issues.
we then went on a 16 ds 2 16 qam ubr. congestion went for about 1 week.
we then went on to 24 ds. congestion went for about 2 weeks.
So I take it they need to split up the network even further...
I also think we have some upstream congestion as the packet loss / ping times is dependent on the upstream channels its locks on.
See the below graph (The total packet loss is me reseting trying to get on differnet upstream channels). There is no downloading or streaming taking place at these times either.
